Hi,

I took advice off 3 people (Zen Performance, Scooby World + another source) and on the 1999 model they have a very sensitive MAF sensor so changing the normal panel filter for an iduction kit it a very bad thing to do apparently.

The best thing to do is just change the penel filter to a performance one and maybe the intake pipe going to the engine.

I found this really helpful adivce, hope it helps someone else!
