HERMAN 33 Posted June 6, 2010 My GTi6 conversion is nearly ready for an engine start and I will be buying a filter for it soon. I am looking for recommendations for a good quality filter. I remember reading an artical somewere that they are not very good at filtering the air in comparision to the standard paper type filters? Which make is the best for good filtration? What is other peoples thoughts? Thanks Neil Share this post Link to post Share on other sites
lemmingzappa 75 1 Cars Posted June 6, 2010 Either Green Cotton or K&N. You can't really go wrong tbh. I wouldn't buy a generic universal jobby off eBay though. Share this post Link to post Share on other sites
Batfink 201 Posted June 6, 2010 The way they work is a cotton or foam gauze with oil suspended on it. The oil catches the dirt as the air passes. As the filter collects dirt and degrades in filter performance, the flow of air is relatively unaffected. For filtration performance paper has smaller holes, but is a restriction which gets worse as the dirt blocks flow. Share this post Link to post Share on other sites

HERMAN 33 Posted June 7, 2010 Thanks for the replys guys. From what you are saying then Batfink, It is always a good idea to clean and oil them on a regular basis? Thanks Neil Share this post Link to post Share on other sites

Eunosfield 0 Posted June 8, 2010 K&N I'd say is the way forward, I've never had any problems with them in any of the cars I've owned, and as long as you don't mind oiling them occasionally they last for ages Share this post Link to post Share on other sites
