JSR Ported FK8/FL5/DE5 Acura Integra Type S Intake Manifold "Porting Service Only"
We completly revamp the internal runners of the manifold and everything inward 4-5". The competitors "port work" is just a simple port match and re-work 2" past the intake flange. As some of you know the inside runners have very sharp turns and transitions, we are able to reshape and increase the ports and round them out which increases the air flow and it's characteristics.
The flange is also ported to maximize air flow which results in more power on the same boost levels.
We have seen 20WHP on the same 30psi vs a non ported intake manifold, so yes, they do work.
The Race Version contains more internal runner work where air flow is increased due to much more material removal.
Street Port Version (450WHP and Below)
Ultra Race Version (450-550+WHP)
Please make the correct selection.
This is for Porting Service Only, you must mail in your manifold for porting. Typical turn around is 3-4 Days before packing up and shipping back out and does not include weekends or Holidays.
