Frequently asked
How do I know a part will fit my car?
Enter your registration above and we cross-check against the TecDoc catalogue to narrow the list to oil filters listed against your vehicle. Specifications can still vary between trim levels and engine variants, so we recommend confirming the part dimensions against your existing component before fitting.
What brands do you stock?
We stock established manufacturer brands sourced through trade channels. The brand row at the bottom of this page shows which manufacturers we carry for oil filters. We don't sell unbranded parts.
How quickly will my order arrive?
Most orders dispatch from our Northampton warehouse within 1–2 working days. Free standard delivery on orders over £40 to most UK mainland locations.
What if the part doesn't fit?
Please check our returns policy for the current terms. If you're unsure about fitment for your specific vehicle variant, please contact our team before ordering using the details at the bottom of the site.
Can I check fitment before ordering?
Yes — every product page shows whether the part is listed against your selected vehicle. Where multiple sizes exist for the same vehicle, the dimensions are shown so you can compare against your existing part. If you're unsure, contact our team for help confirming the right option.
About Oil Filters
Our oil filters range is built from established UK suppliers and trusted aftermarket brands. Each product is mapped against OE/OEM references and TecDoc ktype data so the reg-lookup above filters to only the parts that fit your specific make, model, engine and trim.
Enter your registration to see exact-fit options — or browse by brand using the tiles above. The full catalogue covers most major makes and models on UK roads, with same-business-day dispatch on stock items ordered before 2pm.
When to replace your filters
Filters are service-interval parts — oil, air, fuel and cabin filters all have manufacturer-specified replacement intervals, typically every 15,000-30,000 km or annually, whichever comes first. Skipping a filter change can cost more in engine wear and reduced fuel economy than the part itself.
Common signs a filter needs changing
- Reduced acceleration or fuel economy — restricted air filter limiting intake.
- Engine misfires — a clogged fuel filter starving the injectors.
- Cabin air feels stale or musty — pollen filter saturated.
- Oil pressure warnings — restricted oil filter, or a bypass valve issue.
Choosing the right filter
Filters are tightly engine-specific — even within the same model year, different fuel-system variants use different parts. Our reg-lookup maps to the exact OE part number for your engine code, so you can be confident the cross-reference works before you order.
