I have a VWR intake and as they say it could be a re badged ITG one but if you can find one of them that's an enclosed filter your doing better than me, because I couldn't find one for love nor money..!!
I didn't go for other filters as I'm not a fan of the noise of the open ones..
The build and fit of the VWR one is as expected.. Quality...!!!
I like the noise, you can really hear the turbo through it and you do get a flutter when letting off...
Next mod is a bigger head shield over the manifold and some heat reflective tape on the intake pipe, as it draws cold air from the front grill rather than having to pipe up to an open filter to stop it sucking in hot engine bay air, it's a win for me ..!!!
But like every thing on here, it's different strokes for different folks.. But it suits me and I like it..
