Oil Filters & Filter Adapters

Which filter should catch wear particles before they reach the bearings and turbo? This category brings together oil filters, filter adapters and filter covers for petrol and diesel engines. It is for you if you maintain an everyday car or are upgrading the lubrication system in a project with an oil cooler or a relocated filter.

Oil filters, adapters and covers

The oil filter keeps wear particles, soot and dirt out of the engine oil. The filters come from brands such as K&N Engineering and aFe, whose Pro GUARD filters are available in both D2 and HD versions. A filter adapter can relocate the filter, change the connection or provide ports for, for example, an oil cooler or gauges. What it can do depends on the product. Among other things, we offer adapters from Torque Solution for the Ford Mustang GT and Nissan GT-R. This category is part of our oiling systems together with oil pumps.

How to choose an oil filter

• Fitment: the thread, gasket diameter and filter length must suit the engine and the space around it. Always check the part number against your engine.
• Filtration: the filter media determines how small the particles it captures are, but it also affects flow. A finer filter is therefore not automatically better.
• Valves: the bypass valve and anti-drainback valve can affect oil pressure at cold start and high revs.
• Service interval: choose a filter that suits the oil and the change interval you use.

If your project uses a dry sump system, filtration is typically mounted externally. The choice then depends on how the system is built.

Installation and maintenance

Lubricate the filter gasket with a little clean oil and tighten according to the manufacturer's instructions. This is typically done by hand. When fitting an adapter, make sure the old gasket has been removed. Also check for leaks and oil pressure after the first start. It is common practice to replace the filter at every oil change.

Frequently asked questions

What is the difference between an oil filter and a filter adapter?

The oil filter cleans the oil. The adapter sits between the engine block and the filter. Depending on the product, it can relocate the filter, change the connection or provide ports for, for example, an oil cooler or oil gauges.

Can a filter adapter affect oil pressure?

It can if it is installed incorrectly or if the hoses and fittings are undersized. Check the oil pressure after installation and follow the manufacturer's instructions for gaskets and tightening.

Why does a new oil filter leak right after the change?

A typical cause is that the old filter's gasket is stuck to the engine's flange. The new filter then does not seal properly. Always check the flange and lubricate the new gasket with oil before installation.
