This is our latest design which has even more improvements, for example: Straight through PCV passages, this revision no longer requires swapping the intake manifold to maintain factory PCV function, reuse your stock lower intake. The core itself is more efficient, 20% denser core, and the shape is optimized for the actual airflow path. Internally it is no longer sealed by RTV, it uses o-rings with machined o-ring passages. It is ¾ of a pound lighter than our old Stage 2 core. It has ¾” nipples instead of 5/8” for increased water flow. …And finally, improved machining quality.
It is still a 2.25" core (like our last one) and will fit under most stock hoods with no modifications, but we do recommend adding our cradle spacers. It supports temperature drops of 110-160 degrees depending on blower speed and boost level.
ZZPerformance is the leader in intercooler research, testing and performance. We are the only 3800 vendor with a supercharger dyno. It measures blower CFM, temperature of ambient air, air out of the blower, and air below the intercooler core. In addition, we measure pressure above and below the core, water GPM into the core and temperature of the water going into the core as well as out of the core. By testing over a dozen parameters with various conditions, we are able to bring you performance unparalleled by any other manufacturer. While they guess at what 'should' perform, ZZPerformance can guarantee it!
Pricing includes longer stainless bolts to hold down the blower.
Note: Gaskets must be purchased separately, which can be found here.
Gen 5 M90s have the throttle body inlet higher than on the Gen 3 M90s, please email if you have questions about clearance issues when using a Gen 5 M90.
Fitment note: Has been used in some Holden/Australian applications but we cannot confirm full fitment and functionality.
