Fits all 1ZZ engines with the standard water pump and alternator pulleys installed, no air conditioning, no power steering. If you have a stock MR2 Spyder and remove your AC then this is the belt that you need. MR2-S idler pulley (goes in power steering pump spot) must be used.
Gates is a leader in both OEM and aftermarket accessory belt production. It is the only belt MWR relies on for all projects from stock to heavily modified engines, street to endurance racing.
