This LS1/LS2 front-sump oil cooler kit allows you to get creative with your build. It is designed as a DIY kit to allow you to customize fitment on your highly modified LS vehicle. This LS oil cooler kit requires custom brackets to be fabricated to mount the cooler in your desired location. Included in the kit is a CNC-machined oil line adapter to allow the use of --AN fittings. The 25-row cooler has the cooling ability to drastically drop oil temperatures, and due to this we recommend that this kit only be used on race vehicles. During testing this kit drop oil temperatures by a massive 65 F. This is the kind of set-up you want for your turbocharged or supercharged drag vehicles.
