Product Description

The Brian Crower BC3130 intake valve set is engineered for precision performance in the 4B11T 2.0 L turbocharged I4 engine found in the Mitsubishi Lancer Evolution X (2008–2015, GSR and MR models). With stock-spec 35 mm sizing, these valves offer an ideal balance of OEM fitment and enhanced durability. Featuring a heat-resistant stainless steel build, a friction-welded Stellite tip, and an undercut, swirl-polished stem, these valves boost throttle response, reduce reciprocating mass, and withstand high boost and high-RPM conditions.

Manufactured for both maintenance and moderate performance applications, the BC3130 valves are a direct replacement that upgrades reliability without altering flow characteristics. Sold as a full set of 8 intake valves, installation is straightforward with no modifications required for OE valvetrain. Always verify compatibility with your engine’s tuning stage and consult a professional for installation.
