This is especially true in quite a few GM LS LT1 and LT4 applications. Designed to fit perfectly over the PH3506 or ACDelco PF48E (GM# 12690386) and similar oil filters that measure 3.10″ diameter by 3.25″ tall. 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. The construction of this blanket incorporates a magnet 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. Related products Sale!
