Just installed the MS-201-BK (spin on oil adaptor) on my 2023 Jeep Wrangler JL along with the vacuum pump relocation bracket. I had to call Kevin for help, all went great, Top notch customer service. I fully recommend Baxter Performance.

I recently installed this along with the Dorman updated aluminum oil filter housing. This eliminates the 2011-2013 original oil filter housing which has the problematic oil bypass valve that can come apart. My vehicle is a ‘12 Chrysler 200 Touring convertible. I no longer have the momentary groan at startup.As a car enthusiast I don’t mind the extra step or two at an oil change because I believe it helps with longevity of the Pentastar engine.

I installed the Baxter kit on my new - 2024 3.6 V6 Pacifica. It has been 6,000 miles and the engine starts without the noisy rattling that it had when using the OEM filter setup. Glad I did the install.

I purchased the PENTASTAR 3.6 2011-2013 MS-101-BK CARTRIDGE TO SPIN-ON ADAPTER for my 2012 Jeep due to the clattering when the engine is first started for the day. Very easy to install and it does what it claims to do. I now have no clattering when the engine is first started. Well engineered and very good machining. I highly recommend it to anyone who owns a Jeep with the Pentastar Engine. Thanks!
