As before mentioned I draw a distinction between using oiled filters on road cars to replace the OEM filter and the use of TBs with oiled filters on race cars (and tuned road cars). All the dyno performance tests are done with clean filters. If you are looking for a very small performance gain on a road car and are prepared to clean the filter about as often as you grease the front suspension then the choice is yours. All the tests show that as soon as the oiled filter gets dirty any small performance gain is lost.

Personally I have already done a fair bit of research, including talking to Jenvey and Omex, and when I fit TBs I will have no choice, at least initially, but to use an oiled foam filter and accept what that entails. And, yes, I will be considering fitting a bonnet scoop.

I am always interested to see what Cereal is doing smile
