Tomei PONCAM Camshaft - Nissan VQ35DE G1 EX 258-10.20

Description

Upgrading the Valve Springs is required when using Camshafts with Cam Lift greater than 11.0mm (sold separately). When using Camshafts with Cam lift greater than 11.0mm on the intake side there is a chance that the valves can come into contact with the piston when the eVTC advances the timing. In this case it is highly recommended to recess the pistons to guarantee adequate clearance. Example: The standard advance amount with the stock head and stock pistons with the eVTC will require approximately 1mm valve recess on the piston.
