Hengst Filter: understand the range before choosing
Hengst Filtration develops filtration systems and replacement filters. This AutoMotoPart page contains five insert references: one E1328L-2 air-filter set and four oil-filter inserts—E159H D311, E159H01D311, E603H D198 and E640H01. Similar dimensions do not make these references interchangeable, and a catalogue application must be resolved to the exact vehicle, engine, transmission and production detail.
AutoMotoPart currently lists 5 Hengst Filter items. The largest Hengst Filter groups are 4 oil filter entries, 1 air filter entry. Hengst Filter totals can change, so a category count is orientation rather than proof that a particular reference suits a vehicle, workplace or job. The exact Hengst Filter listing, its current technical information and the item in front of you must agree.
What the Hengst Filter page actually covers
| Product group in this range | Current entries | Selection focus |
|---|---|---|
| Oil-filter inserts | 4 | Match the complete Hengst reference, dimensions, seals, filter housing, vehicle build and service circuit before installation. |
| Air-filter insert | 1 | Confirm both-sided air-filter quantity, housing shape, seals and intake connections without inferring a vehicle from dimensions. |
Four entries are oil-filter inserts and one is an air-filter insert. The catalogue codes carry decisive punctuation and suffixes: E1328L-2 indicates the exact air-filter reference, while E159H D311 and E159H01D311 must remain distinct. Keep the product package with the job record until the service has passed its leak, level and installation checks.
Build a reliable shortlist
Build the shortlist from a current application record, not from vehicle model alone. Record the VIN, exact engine and gearbox codes, production date and any catalogue restrictions. Open the housing only after the circuit and replacement procedure are positively identified.
| Check | Why it matters | Useful evidence |
|---|---|---|
| Reference | Spaces, hyphens, D suffixes and H01 distinguish real products | Full Hengst code on lookup, pack and removed insert |
| Application | One model can use different filters by engine, build or transmission | VIN, engine code, gearbox and production breakpoint |
| Dimensions | Near-identical inserts can differ at an end seal or bore | Height, outer diameter, both inner diameters and end profile |
| Seals | A wrong, doubled or misplaced O-ring can leak or bypass | Supplied seal set, groove position and service illustration |
| Circuit/fluid | Engine oil and transmission fluid require different procedures | Housing location, workshop procedure, fluid grade and level method |
| Final checks | A filter service is incomplete until flow, level and sealing are verified | Torque value, priming/start sequence and leak reinspection |
Do not cross-reference by size alone or assume that all applications shown against a family use every filter listed on the page. A current exact application result and the physical housing must agree. Where a supersession is claimed, verify it in Hengst or vehicle-manufacturer information before use.
E1328L-2 air-filter identification
Hengst's official catalogue identifies E1328L-2 as an air-filter insert and gives 301 mm length, 306 mm secondary length, 193 mm width, 193 mm secondary width and 97 mm height. It also states two inserts per individual package. The live product evidence says fitting position on both sides, so quantity and left/right housing arrangement must be checked rather than assuming a single panel.
Before removal, photograph duct and sensor routing if useful. Open both housings without dropping fasteners or dirt into the clean intake. Compare the two new elements with the removed pair, clean only by the approved method, seat the perimeter seals without folds and close clamps evenly. Refit every connector and inspect ducts for splits or an unseated joint.
E159H D311 versus E159H01D311
These two oil-filter names are deliberately similar, but their codes and inner dimensions differ. E159H D311 is recorded at 54 mm outer diameter, 202 mm height and 15/22 mm inner diameters. E159H01D311 shares the 54 mm outer diameter and 202 mm height but is recorded at 15/21 mm internally. Both listings mention included gaskets or seals.
Retain the H01 element of the second code and compare end-cap profile, centre tube engagement and seal kit. A one-millimetre stated bore difference is not a tolerance invitation. Do not transplant an old O-ring onto a new cap or choose whichever insert slides into the housing; use the exact application and illustrated service configuration.
E603H D198 and its transmission qualifier
E603H D198 is listed as a 44 mm outer-diameter, 132 mm-high insert with 23 and 21 mm inner diameters and supplied sealing parts. The evidence includes the qualifier ‘for vehicles with automatic transmission’. That narrows an application record but does not identify a gearbox family, prove universal automatic fitment or tell the technician which fluid circuit is being serviced.
Locate the housing from the vehicle procedure and identify whether the job concerns engine lubrication or transmission filtration before draining anything. Transmission level checking can depend on fluid temperature, selector sequence, vehicle level and diagnostic data. Engine-oil service has its own fill and priming requirements. Use only the applicable procedure and specified fluid.
E640H01 compact oil-filter insert
E640H01 is the shortest insert here at 73 mm and the widest outside at 70 mm. The recorded inner dimensions are 31 and 27 mm. Hengst's official Connect page identifies article 4175130000 and EAN 4030776065183 for the E640H01 oil-filter insert. Those identifiers can help resolve a damaged or incomplete label, but vehicle application still requires the current lookup.
Inspect the housing cap, centre stem and seal groove before assembly. Remove the old O-ring rather than placing a new one over it, clean the groove without scratching it and install the correct new seal in the illustrated position. A seal fitted on a cap thread or flange by intuition can distort, leak or prevent the cap reaching its specified seat.
Controlled filter replacement and verification
Work on a safely secured vehicle and protect against hot components and fluid. Clean around the housing before opening, note the old insert orientation and allow it to drain into a suitable container. Compare old and new parts side by side, including code, length, diameter, end details and every seal. Stop if the old filter has collapsed media, metal debris or unexpected contamination that needs diagnosis.
Fit without forcing the element, renew all specified seals and tighten with the correct tool to the vehicle maker's torque. Refill by the exact quantity/level process, complete priming where stated, start or run through the prescribed sequence and inspect under good light. Recheck the level and housing after circulation; never dismiss fresh wetness as residue until it is cleaned and confirmed not to return.
From identification to a checked result
| Stage | Good practice for this range | Mistake to avoid |
|---|---|---|
| Resolve | Identify VIN, engine, gearbox, build date, circuit and exact Hengst code | Selecting from model name or dimensions alone |
| Prepare | Cool, secure and clean the housing area; obtain fluid, seals and torque data | Opening the wrong circuit or introducing debris |
| Compare | Check insert code, every dimension, end form and seal set | Treating a near match as interchangeable |
| Install | Use correct orientation, fresh seals, clean specified fluid and cap torque | Doubling an O-ring or forcing the cap |
| Verify | Prime/run, set fluid level and inspect for leaks by the stated procedure | Returning the vehicle without circulation and recheck |
Record the full Hengst code, vehicle identifiers, fluid used, cap torque and final level/leak result. For E1328L-2, note that both housings/elements and all disturbed intake connections were checked. This traceability is more useful than relying on memory at the next service.
Reading real Hengst Filter references
The Hengst Filter names below are examples from the current range and show why the complete description matters. They are not universal Hengst Filter recommendations and should not be treated as a fitment list. Within Hengst Filter, a shared family word can conceal a different dimension, connector, material, pack format, operating condition or installation side.
| Example listing | What to verify beyond the name |
|---|---|
| Hengst E1328L-2 Air Filter | E1328L-2, 301/306 × 193/193 × 97 mm, two-sided housing and package quantity |
| Hengst E159H D311 Oil Filter | E159H D311, 54 × 202 mm, 15/22 mm bores and exact supplied seals |
| Hengst E159H01D311 Oil Filter | E159H01D311, H01 retained, 54 × 202 mm, 15/21 mm bores and end profile |
| Hengst E603H D198 Oil Filter | E603H D198, 44 × 132 mm, 23/21 mm bores, exact automatic-transmission application |
| Hengst E640H01 Oil Filter | E640H01, 70 × 73 mm, 31/27 mm bores, housing cap and seal groove |
All five titles carry enough detail to prevent casual substitution when read in full. Still, measurements are a cross-check after application identification. Do not turn this five-row page into a generic vehicle fitment chart.
Common errors around Hengst Filter products
- Dropping spaces, hyphens, zeroes or the H01 suffix from a Hengst reference.
- Assuming E159H D311 and E159H01D311 are interchangeable because height and outer diameter match.
- Reading the E603H D198 automatic-transmission qualifier as universal automatic fitment.
- Choosing an insert by diameter without resolving vehicle, engine, gearbox and circuit.
- Leaving the old housing O-ring in place or fitting the new seal in the wrong groove.
- Using an unspecified fluid to lubricate seals or refilling with an assumed grade/quantity.
- Allowing dirt into an oil gallery, filter housing or clean side of an intake.
- Skipping cap torque, priming, temperature/level procedure or final leak inspection.
