Cosworth Billet Timing Belt Guide Subaru WRX STI EJ25 & EJ20 02+
The original sheet metal timing belt guide can flex from belt deflection when subjected to extreme rpms causing the timing belt to skip one or more teeth on the crankshaft sprocket. The Cosworth Billet Timing Belt Guide was developed to control this problem and is machined from solid aluminum with a hard anodized finish. Includes mounting hardware.
