Induction kit

[Guest]

Hi,
Has any one installed a K&N induction kit?

IF so does it improve performance?, what does the car sound like?

Many thanks

Fitted K&N induction kit to my 8v Lux and wasn't over convinced about any increase in power. Have now changed to a different shrouded induction kit as part of more extensive engine rebuild and chipping - responsiveness of the car is definitely increased but how much of this is the kit I don't know. As for the sound, the shrouded intake gives a great throaty grunt.

The main worrie would be that water would get sucked when it rains.

IIRC the filter perforation size makes in resistant to the ingress of water drops. This is further assisted by the oil coating. It will pass water if submerged - in which case you are in big trouble- and will allow water through as a harmless vapour. I used to run my Westfield with a foam filter exposed to the ellements and this was never a problem.

I wouldnt bother myself. Id expect to see a reduction in performance as your engine ingests hot air...

haha i have just done a search and come to the same conclusion ill just stick with the standard set up..feel a bit embarrass t for asking now[8|]

The only one ive been considering, mostly to go along with my MAF conversion project is to get a piper cross venom enclosed foam filter with a cold air feed.

One of the issues facing a change of anything in the intake/exhaust system for the 944 is that the DME ignores the AFM at high air flow and full throttle. This means it injects based on what the airflow would be on a stock engine at that RPM/Air temp. This will result in some change in AFR, could be better could be worse .

I'd say go for it. I have them on both my cars, they're worth it for the noise alone []. I didn't notice any loss of power even during extended track sessions but it's dead easy to pipe in some fresh air if you're worried about that. The engine seems to rev more freely with them, but I'm prepared to accept this could be entirely psychological.
