Hi guys,

Can someone recommend a low restriction air filter? Panel/ cone isn't important as is modification of the air box/ tubes.

Many thanks.

Don't do it.

All the independent testing I've seen published usually shows aftermarket so-called performance air filters do not increase power and may even decrease it. In addition they are less efficient at filtering out particles that wear out the engine.

Much better (and cheaper) to just use a good quality OEM air filter and change it more frequently than the recommended service interval.

The results vary massively depending on the stock induction system and the design of the after market system. There are plenty of cars where replacing the stock induction system with a good after market system gains some power.

One of the key requirements for most vehicle manufacturers when designing the induction system is to reduce noise, if you don't care about that you can potentially build a better flowing system, but it depends a lot on how good the stock system is.

And worse of all, the oil filters are coated with can damage the air flow meter.

They are a pain. They always look dirty
