AFR - Air Flow Research

"AFR has been a major player in the cylinder head game for over 50 years, and these 2 examples show you exactly why.

On one side, you have their LSx 210 cc Enforcer heads, featuring their Permanent Mold “As-Cast” Technology surfaces on the intake runners, exhaust runners and combustion chambers that allows for extremely accurate and repeatable port location/performance.

On the other side, you have their 270cc LS3 cylinder head, featuring 100% CNC Ported Combustion Chambers, 100% CNC Ported Exhaust Ports, 100% CNC Ported Intake Ports, and a Competition 5-angle Valve Job. These heads are made to help your engine breathe, and are designed with high boost in mind."

Featuring a large, race-proven plenum and precision-tuned runner geometry, the Magnum intake delivers exceptional cylinder-to-cylinder distribution and high-RPM efficiency. The 4500 Dominator fl**ge provides the airflow capacity required for aggressive camshaft profiles and high-demand fuel systems, making it an ideal choice for naturally aspirated race engines as well as power-adder applications.
