Every combustion engine relies on oxygen to get a good, clean burn. With the extra burst of oxygen from one of these DOC kits, your fuel's oxidization levels will increase, boosting your engine performance and fuel economy in the process.

These kits are built to last, using only the strongest high-grade stainless steel in the canning and elsewhere in the hardware.

Not only are these kits brand new, completely free from oppressive core requirements, and more affordable than OEMs, they're also guaranteed to be an exact fit for your machine. That means no more guesswork and wasted hours buying the wrong hardware for your project. Simply click and pick the part you need with the exact measurements you want and that's what you'll get.
