PRICES AND LISTINGS ARE SUBJECT TO CHANGE AT ANY TIME WITHOUT NOTICE. We stock the same parts from different manufacturers so that when back orders occur we have a part that is equal in quality and cost to send, preventing what can sometimes be long waits.

This would be the only reason your order might vary slightly from the description, and the part that is subbed will always be comparable quality. If you only want a specific brand just ask and we will let you know if it is out of stock and for how long. Once a part has been installed or prepped for installation it is no longer eligible for return. This product is NOT DIY. Over 99% of people in the world are not qualified to build an engine, and it is the responsibility of the person assembling and tuning the engine to make sure all the parts are correct and work properly.

We ALWAYS STRONGLY recommend work be done by a qualified, experienced mechanic. Please work with us and we will ALWAYS work with you.
