Intake Manifolds Performer RPM Air-Gap, For Holden, Commodore V8, VN Heads 253, 304, 308|SPELAB
SPELAB Performer RPM Air-Gap intake manifolds incorporate race-winning technology that's been used on Victor Series competition intakes for years. The open air space from the Air-Gap design separates the runners from the heat of the lifter-valley cover. So, the air/fuel mixture stays cooler all the way to the heads, which produces a denser charge for more power. Runners are tuned to move the power band 1,000 rpm higher than Performer Air-Gap manifolds, from idle to 5,500 rpm up to 1,500 to 6,500 rpm.
