Hi,I think Green panel are best,looking at around £40 for one from any good company.
 
Hello mate im runing a pipercross panel cost about £35 i think.
If your near Essex give Shaun at AmD a ring.
Have you thought about smoothing the airbox aswell its well worth it
 
Yes mate best mod for the money
Smooth the inside, top and bottom and remove o/e feed pipe and replace with 3" feed pipe
 
I got a green one from Badger 5 (bill). I replaced the jabba induction kit for it, and it is now smoother and more responsive too.
