VWR Intake disappointing
shoaybmakda:
I didn’t have issues with the MAF on mine..it was a little snug from what I remember but slotted I’m ok..

One good aspect of it is the MAF scaling is spot on with these kits from everything I have read about them over the years, so it doesn't ruin the drive. The RamAir however does not and has a detrimental affect on off boost and part throttle driving. Been there and tested it

Was it the 70mm or 90mm Ramair you tested? And were the scaling issues tangible during driving?

A picture paints a 1000 words. As you can see, the VWR pipe had to be modified on mine to match the OEM airbox's MAF aperture.
If I didn't do that, the MAF wouldn't have sealed down onto the pipe at all. I'm surprised no one else encountered the same issue!

90mm, but it makes no difference, both use the same MAF pipe which results in the same issues. And yes very much so, turned my car from feeling spritely and eager to feeling sluggish and lethargic during day to day off boost driving..... Like how the car feels after having sat in traffic on a hot summers day... It lasted less than a day before i removed it and went back to my other intake which has long term fuel trims within 1%

Hmmm. I've never really felt any loss of torque or response that I could categorically attribute to the 70mm version I've got - although I'm not saying you're wrong (in fact, I'm probably more receptive to reasoning against the thing, than for it).
There have been odd occasions coming onto boost where I think "Is that it?", where it just feels a bit limp and not producing the thump of torque you expect, but this has been both before, and after the Ramair went on, so something I'd probably put down to heatsoak at the time and not given a second thought.
One thing that is consistent, is a marginally stronger pull from around 4k. So it's doing something. I'd give it maybe 10bhp/10lb/ft at 5252 going by the seat of the pants.
I like the noises on full chat, but rolling around - especially on a cold engine - can get tiresome. It's all a bit wheezy and chuffy.
I'm inclined to ditch it. Certain elbows are uncomfortably close to coolant hoses and other more important bits. I think if I went k04 and back to a standard box I wouldn't miss it.
Anyway, here's the real question. Why don't you and Pudding co-develop an intake that ticks all the boxes? You've both got the ability to make it happen. And I'd buy one. Undercut VWR for a start.
