As we all know how hot turbochargers get, some of that heat can transfer to the oil filter itself.

Designed to fit perfectly over the Mopar MO-285 and similar oil filters.

The extremely durable pulverized lava rock material we constructed this blanket with is capable of handling over 2000° F direct contact heat.  The cover easily helps keep heat off the filter in turn reducing engine oil temps.

Install is very easy and stays in place between oil changes.

The construction of this blanket incorporates a series of magnets to help keep the cover in place.  The magnet also helps boost the oil filters efficiency by catching any fine debris and keeping it at the now magnetized surface of the filter.

The pull handle on the end of the blanket makes removal extremely easy before removing the oil filter.

The aluminized internal layer helps make any accidental oil spill extremely easy to clean off the cover.

This blanket is manufactured with stainless steel capstan style lacing anchors and  a high density ceramic inner lining capable of handling 2500°F direct contact heat.

The exterior of the blanket is made from extremely durable and heavy duty two part aluminum bonded pulverized lava rock material capable of handling 2500°F.

Is is easily installed with the supplied stainless steel wire and without having to remove any components.
