This Duracon TRD Oil Filler Cap has been designed for endurance racers in mind as well as for those wanting to dress up the engine compartment.

Duracon does not absorb much heat, so it will be significantly cooler than the surrounding engine components, thus making it easier to handle after a spirited drive or track day!

Fits most Toyota engines. 

Does NOT fit 20V 4AGE valve covers or any Toyota w/out threads.
