You can notice a difference, Both Rhys and I agree on this.

 It makes is more responsive, nick from R-tech did tests on different intakes and found the DSG mod and pipercross to be the best all round set up.

The pipercross is reusable and helps with air flow.  You will get more of a dump sound and induction note.  :smiley:


(Knowing your luck it wont make any difference to your car and you will say its crap  :grin: )

no dude that was just standard airbox/filter vs pipercross

airbox smoothing is a bit pointless, the fins act as tumblers to evenly distribute the flow across the face of the filter so you dont end up with it sucking all the sh!t into one corner. Performance panel filter in a standard box is good enough, CAI is marginally better.

Aye, remember reading your spec list :) It'd be nice to push the most outta it I can but cost effectiveness will go out the window if I do a full exhaust lol.

It's got a stealth stylee backbox on it, sounds ok quite deep and bassy, I'd like a bigger downpipe and sports cat ideally but we'll see.

See thats why I asked about the smoothed airbox. I have been googling and a lot of people say 0 gain. Some people say placebo effect. Some people say it sounds a tad louder, louder dumping/chattering noise...but no noticable gain purely from smoothing the airbox.

Confusing times, dunno wether to bother or not after I read all that hence asking the experts :)

I think your right with the placebo affect.. just like the vr6 clutch upgrade because its single mass flywheel instead of dual mass you automatically assume its lighter and it turn giving better acceloration when infact single mass was slightly heavier.. Your mind works in mysterious ways lol

Not all single mass flywheels are heavier. There heavier if you buy the wrong one. :grin:

I probably bought the wrong one haha. It seems a bit revvier, responsive though. But a negligable amount, so yep - placebo effect haha.

Gonna do a bit of searching for the r-tech filter comparison tests if I can get search to work with 2 words or more! lol :)

Now your asking mate lol

I read the thread Hulmie and i swear if you get the vr6 flywheel from VW its slightly heavier no ?? I thought the only ones that are lighter are ones like the 14lb one from ECS etc..
