Designed with the higher RPM of the SR20 in mind, we modify the stock runners to flow better at higher RPM, using our two piece manifold/plenum design to allow easy future modifications without cutting and welding, porting, polishing, increasing or plenum volume. With optional velocity stacks, end feed or side feed plenums (shown) available that bolt on, this is the only manifold available with built in versatility and adaptability.
The standard manifold price includes the welded flange on the factory runners, new Xcessive end feed plenum with 4 vacuum ports, new stainless throttle bracket, 10 plenum bolts, two vacuum fittings (1/8", 3/8") and two vacuum port plugs. Factory throttle body not included. For options like velocity stacks, polishing, powder coating, larger throttle bodies, or whatever you can come up with, give a call or email. 503-504-2147 or rich@xcessivemanufacturing.com
An $80.00 core charge is applied for the runners. It will be refunded upon Xcessive's receipt of your old runner set. The $80 is applied in the shipping calculation and will be refunded via mail. If you have a set of runners you would like to have used (ie. polished, coated), please contact us prior to ordering.
