Induction Kit

[Stu08]

Hi everyone,

Does anybody know of a good cone filter which has a good cold airfeed and heatshield as part of the kit? Really want to go down this route. Anyone have any experience?

Thanks,

Stu.

majority of induction kits have showed negative results on this engine due to air intake pipework

do the air box mod with a panel filter

they perform badly due to them allowing hot air from the engine.
A modified airbox can allow enough air for 200+ bhp

Thanks guys, was thinking I wanted more induction noise, my car is a vec c 2.2 sri, forgot to mention that bit! I have heard you can drill the airbox and fit a panel filter. I have a question with regards to this though. Does drilling the airbox disrupt the airflow or have any negative effect on the engine which could cause potential running problems?

Thanks for anymore help

no not really

all depends where u drill the holes

i have known people to drill a good 500mm hole and stuck in another air intake pipe next to the existing pipework

500mm mike? that would be a nice size intake but the box aint any more than 200mm wide

50mm

I recently drilled two 32mm holes into my air box. Didn't get much more induction noise, but could really here to turbo spool up. I've since gaffer taped them back over, as the sucking noise it was making wasn't actually that nice to hear.

Both mine and alys 2.2 airbox's on our 2.0 turbos have around 20 15mm holes drilled on the inner wing side of it below the filter, makes a nice induction noise and can here the dump valve alot more than without....

I think mine sounded s**te because there was just the two. I bet yours is louder as well without the cross over pipe.

yeah the xover pipe removal does make a diff imo....

Decided to give modifying the airbox a shot. Friend helped out as me + tools = A&E. Removed the lower plastic in the airbox, to improve things on the noise side we drilled ten 22mm holes on the inner wing side of the airbox below the filter. The car does sound alot deeper now under acceleration.
