It's a cone type filter ie the e-2993 part number from on. Less power how come? Due to the fact that the engine would need to be 're calibrated? I assume that would be right but I would of thought that it would help a little bit by being less restrictive so that the turbo has a bit more of a chance to spool up better without strain of my right foot
Ive never used a K&N but Green argue that their filters are better because they dont use machines to bond them like K&N
Green show K&N filters with glue covering the edge on the cotton restricting flow,
Green dont have this problem.
And to confirm,
If using your existing air box enclosure,
An upgrade induction filter will help both performance and mpg.
But if removing the air box enclosure to fit an exposed induction filter, then these suck in heat, but panel/air box filter upgrade is a good option.
And as far as im aware Ross at pri racing still has the exclusive offer of 10% off
See my fitting guide for the discount code.
Or if you really want to maximise induction, You could fit a K&N 57s system consists of bigger air box lid to house supplied bigger fiter plus optional cold feed side inlet port. Im tempted myself http://www.autospecialists.co.uk/KNs-57S-Performance-Airbox-Lid--Performance-filter-upgrade---57S-4000-Product-1131.html
Here are some pictures of the edge on the green filter, no glue smear.
