/\ Mugen...
By far the best & it's good for over 160kw...
Works with Plenums or Quads

There's a Mugen copy too (out of China), but it's not as good.

Std airbox reaches it's limit around 120~125kw

Comptech... Not a fan...
Can't say for sure if it's crap...
Just all the cars that have them seem to be... LOL
Plus it uses a puss foam filter

Fantastic! I will certainly look in to it, having said that shed some light on some manifolds i am a little restricted i cant use B16A or ITR units cause the flange design is diffrent.

Use the B18C2 std intake manifold & keep the IAB (secondary intake runner) function.
For maximum output use with a 65mm throttle & you'll need to tickle the inside a little.

As I thought, cheers

I know the PTV will also depend on what piston is used however from experience what is safe and ideal?

1.5mm is about as close as you should dare going...

Thanks adz so there really is no point buying a aftermarket fancy manifold, i asked since i do not have a manifold to start with.

For a maximum effort road or track car with zero defects,
Yes the Mugen is a fine choice.
With excellent flow, it lends itself to use with both plenums or quads.

That said,
If you're on a budget & defects are not so much a concern,
Products like Injen, AEM, Fujita etc offer excellent value for money.

The custom CAI with a dyno tuned length & bellmouth intake,
If enough time is spent, will generally deliver the best result with a plenum.
However the cost can be comparitivley high.

thanks for that
