absolutely garbage! DOES NOT FIT 2005 chrysler 300c 5.7! this product is absolute garbage and is made of of cheap materials! save yourself the trouble! the fittings on the hoses are absolutely nothing like the pictures! they used a soft metal that easily rolls over with any kind of force applied required to put the damn thing together, also you will need to do an “EGR” delete prior to install i highly suggest that you go with ANY other brand for your own sake! i would rate -5 stars if possible

Looks good and it’s easy to install. Toke me about 20 minutes. I love that you can buy the engine cover back on. I would have made the left hose a little longer but it works. Will update once I have driven the car for a few months.

It works as advertised, but it’s no more effective than the $15 can I use on my truck, the installation isn’t difficult even with the universal fit cans, if you want 5 minute installation vs 20 minute installation it’s probably for you, if you’d rather spend $40 all in and drill 2 holes and cut 2 hoses you should pass

K & N oil separator was an easy installation that will help protect your engine from sludge. It took around 25 minutes to install on my 5.7 Challenger RT. Picture doesn’t show it but you are able to keep the factory engine cover on, I would definitely recommend it.
