High Flow Intake Manifold

D760-0340
$899.00

Further increases in horsepower and torque are obtained by adding a Dinan High Flow Intake Manifold. The manifolds are ported and polished using the extrude hone process, then powder coated black for a dramatic, high performance look.





they seem to have taken the nice dyno charts off thier site
but speaking with someone that has done this mod and a lightweight
flywheel they say the 535i is utterly transformed in terms of power

any thoughts?

charts and graphs that dinan put up before, using the way back machine. Probably closer to 5 hp with the manifold. thats about a 2.5% increase for 900 bucks..thats a little too steep per hp for me.

well i'm not down with paying dinan's price
that is why i wanna send my manifold to have it honed out on my own...

perhaps it was the flywheel that "transformed" the car?

were i to hone the manifold , matching the intake ports would prolly help too...


oh and this wouldnt be just tacking it on for the hp this would be to compliment the turbo...
