Features & Details

  • Reduces Engine Sludge
  • Reusable Filter
  • Billet Aluminum Body
  • Black Finish
  • Simple Installation
Reduces Engine Sludge. This PCV Pre-Filter acts like a mini catch can by filtering out the contaminated oil left in "blow-by" (a combination of exhaust gases and oil) before the blow-by is recycled back into the intake system to be re-burned, thus preventing the used oil from re-entering the system to gum up your engine.

Reusable Metal Filter. The JLT PCV Pre-Filter features a C&C milled billet aluminum body with a reusable full metal filter that traps nasty power robbing oil vapors, but still allows the PCV air to flow normally back into the system. The filter assembly is reusable and is easily cleaned with brake cleaner or automotive de-greaser.

JLT Pre-Filter Application. The JLT Performance PCV Pre-Filter is sold individually, please check the guide below for the quantity needed for your application.

  • Yes you can. Some people run seperators on the drivers side but the pre filter will work just fine

    Don't know if it works as well as it looks but I'm happy with it. I ordered this as soon as I found out about it because I was redoing the PCV system on my 03 Eaton Swapped Marauder and added a JLT catch can and what better addition than another JLT product for the other side right? I had it 2 day shipped so I could install it that weekend. Received the package opened it up all excited and guess what, it was missing the filter. Well needless to say I didn't get it installed that weekend. I called AM and they shipped me out a new one and refunded me the cost of the 2 day shipping. Received it later that week and installed it and it looks good almost factory like. I would recommend this product to anyone that wants to remove the PCV valve off and use a small filter.

    Good Fit.

    This filter fit pretty well without any modification on the drivers side of my 2004 Mach 1. I have only had it on for a couple weeks now but after taking it off and inspecting the filter it seems to be doing its job and preventing burning oil.

    Good quality but fit on certain applications not the best...

    Excellent quality and design works great on my 04 cobra driver side but on my passenger side (intake side of 03-04 cobra) I had to go purchase a different elbow out of the pre filter and additional hose to get the hose to fit correctly in to my JLT RAI. You really have to try a lot of different options to get it to fit just right and not kink the hose. A person shouldn't have to purchase additional items to get it to work correctly after paying for an item. THIS IS A JLT PROB. not American muscle

    Not bad for the price

    I have the other JLT oil separator for the driver side of my Cobra. Item # 62029. Works awesome. I bought this one for the passenger side of my Cobra. I needed to trim the factory hose a little to get it to fit properly without kinking. Overall, I'm happy with it. Thanks again American Muscle for the quick shipping. It only took 2 days to get it!

    Stops the oil completely!

    I autocross my Mach 1 and the guys at the track said when I would let off after full throttle I would get burning oil smoke. I got worried I had burned a valve or broke a ring. Then I found out that these cars pull oil from the PCV valve. So I pulled the intake tube off of the throttle body and sure enough there was a trail of oil coming coming from the pcv along the inside of the intake tube and into the throttle body. I installed these pre filters on each side of the motor and cleaned the oil off of every thing and went for an aggressive high rpm drive and pulled every thing back apart and it was dry and free of oil. So these are working very well! The driver side needed some fabrication to work but it was easy. I just bought some Heater hose and cut it to length and pushed the pre filter into it and then installed that onto the pcv pre warmer. Then to connect the pre filter to the plastic tube I used a bit more of that hose cut to length and connected the plastic tube to the pre filter plastic elbow. Very easy. This mod is totally worth it.

    Good but just buy an oil catch

    I bought this because I didn't have the cash for an oil catch and I was pleased for a little while. It's easy to install and clean but it doesn't function well. The 4 valve motors suck oil into the intake pretty bad, especially with high mileage. It reduced that slightly for maybe two weeks so I went to clean it and when I pulled it off 3 drops off oil drained back on to the valve cover. And when I sprayed it out not much more came out. It worked again for another week and then oil started pulling through it again so I just removed it and will be buying an oil catch sometime soon.

    JLT PCV Pre-Filter

    Works as advertised. It was made to fit the OEM intake tube, so those of you running CAI will need to modify the rubber tube to fit properly, but it's easy. I have a JLT CAI and it fit fine. Checked the level after the first oil change and there were a few drops of oil in it, so that's a few drops of oil that didn't get burnt.

    This is the Smoke Stopper!

    A few weeks ago I noticed my 2003 cobra hesitate on startup and shoot out a plume of white smoke; I began to panic. After doing some research I found that this is a common problem with the 03/04 cobras caused by the phenomenon known as "blow by." I purchased these pre-filters from American Muscle, received them quickly and installed them in about 5 minutes. Now when I start my car there is no noxious cloud of burning oil, just a throaty growl from my exhaust.
