What cold air intake did you buy?

awesome, makes sense, thanks!

Good link.
I had a BCS CAI intake installed on my Mk6 GTI and the car was running very poorly after that due to wrong MAF readings. There was a lot of drone and lag just under the 2k rev mark. From the outside it sounded like it was struggling for power.
Put the stock intake back on and its now running like a dream again.

Not all CAI are made equal, just keep an eye on this thread: VWVortex.com - Aftermarket Intakes and Fuel Trim Issues

I've got APR stage 1 software with the full stage 2 Carbonio intake. I have done numerous road tests with and without the intake, and it makes a noticeable difference to responsiveness and low end power. The difference in high end in less noticeable but the dyno would probably pick it up. It also makes a pretty cool noise both on induction spool and blow-off/compressor flutter noise, if you're into that kind of thing.

Good to know - I'm picking my car up later today: Stage II ECU, Exhaust upgrade and Carbonio intake
I wanted the car to breath better - the top end runs out of puff (I've been short shifting and driving on torque)

where abouts are you getting the tune/intake/exhaust done?

[Martin]

BWA Auto are doing the work for me
Also getting the Supaloy lower/front control arms

Will an intake that utilises stock MAF sensor location (one that only replaces the intake box) result in fuel trim issues or is that very unlikely?

Not unless air is leaking in on the engine side of the MAF. Potentially makes no difference where the MAF is, as long as all the air entering the engine has gone through it.

Great! Thanks Gavin

diameter of area where sensor is is very important also. all the trim issues with vwr and forge are because the manufacturing process didn't ensure accurate pipe internal diameter.

This is also true, I was making the assumption the diameters were the same.

APR/VW Racing in the USA has come up with a "fix" for the issues with the VWR intake (fuel trim issues). Its a metal sleeve that slightly reduces the diameter of the pipe right where the MAF is.

Wonder if this fix will be offered here aswell??

See here: VWVortex.com - VWR Intake fuel trims UPDATE..

I'm guessing this is only applicable to intakes with the stage 2 piping kit?

Not sure what car you have, but im guessing a MK6 GTi (or another car with that same engine) as you mentioned stage 2 intake pipe.

The info i mentioned above really only affects the Mk5 GTI engine and Golf R engine. Some of the intakes are causing issues with air flow readings.

[Bev]

Oh thats a relief! Yep I have a mk6 gti and just recently bought the new viezu carbon intake.

[Martin]

I just want that carbon engine cover!
