Product Description
If you want maximum protection for your Duramax fuel system, the Sinister Diesel CAT Fuel Filter Adapter Kit is the upgrade you’ve been waiting for. The factory filter simply doesn’t cut it when it comes to keeping today’s high-pressure injectors safe. Our adapter lets you replace the stock filter with a legendary Caterpillar 2 micron spin-on filter, providing superior filtration, greater capacity, and longer service life.
Every Sinister Diesel adapter is CNC-machined in-house in the USA from premium billet aluminum and finished in our signature Sinister Blue anodizing. Installation is quick and easy, requiring no modifications. With better filtration, you’ll enjoy longer injector life, reduced maintenance costs, improved performance, and the confidence of knowing your Duramax is protected.
Why OEM Isn’t Enough
Factory filters allow contaminants to slip through that can score injector internals and shorten fuel system life. Upgrading to CAT’s 2 micron technology gives your truck the defense it needs against today’s ultra-fine particles in diesel fuel.
