Cars and trucks like the 03, 04 Cobras and the Lightnings are prone to major amounts of oil being re-circulated back into the intake track through the PCV system. This can cause sticky throttle, clogged intercooler fins, gummed up intake runners, carbon deposits and can even lower the octane rating of your fuel.

With this Pre-Filter from JLT you will greatly reduce the amount of oil that gets into your intake track. It’s a full C&C milled billet aluminum body loaded with a full metal, reusable filter that will trap the oil vapors and allow the PCV air to flow through as it normally would. This filter is easily cleaned with degreaser or brake cleaner. Also included is the rubber seal for the PCV valve to sit into.

This will work on all 96-04 Cobras, Lightning, MACH I, Bullitt, Marauder and most all cars equipped with a standard ¾” base PCV valve (some hose re routing may be needed on some models).

The JLT Pre-Filter is designed to fit on the PCV side of these vehicles, but will also fit the opposite side as well if needed. Most of the oil coming through the PCV system is coming from the PCV side, but can come in the opposite side as well. Check your intake tube for oil to see if 1 or 2 are needed for your application.

Here's what one customer posted online: "Wanted to take this opportunity and give you guys my honest opinion on this controversial piece of equipment. Controversial because there are a few who said that this does not work where others swear by it. I can tell you that I have been running a Steeda Oil Separator for quite a few now. It worked well, and I collected about ¼ or a bit more of the capacity of the container in about 1 month or so of use (all depending on how hard I drove the car), but I was always worried about vapors and oil passing thru this system and contaminating the system specially when running Nitrous or at the top end. So, I keep reading about this pre-filter and about one month ago I finally ordered one of these JLT PCV pre-filters trying to clean up my PCV return even further from oil and other contaminants. I can tell you that my Steeda Oil Separator is completely clean with NO trace of oil."
