XAT Racing exclusive! 1989-1997 1UZFE owners are no longer left out when it comes to upgraded valves! We now supply a full set of 32 oversized valves (16 intake, 16 exhaust) for non VVTi 1UZ engines. Intake valves are 34mm. Pictures shown are of an actual set made for an early 1UZ customer that is looking to push some big HP numbers.

Please note these are custom ordered parts. We do not typically stock a set of them, so expect 1-2 weeks wait time roughly for availability. These have 6mm valve stems and are not for the VVTi engines. We have SuperTech options for anything 1998 and newer.
