It's going well. I reckon you should order it but then I have not tried any other intakes so can't say what's better. The airhammer is a fair improvement over stock. Going by the computer it reckons I'm using less fuel. Approx 0.5-1L/100km less then before I had the airhammer. And it does seems a bit more responsive.
Also the pipe does get very warm as it sits on the radiator. Hopefully when i get the manifold insulators in it wont be as bad.
I'm selling mine, about 2000km old, bit scratched here and there, but basically brand new.
Got a heatshield too.
$400 including postage, includes box, instructions, all parts,etc. PM me
kool. I just put the order through for the manifold insulators. once i check my pay has gone through i'll probably order the airhammer kit tomorrow some time
