      Auxiliary Oil Coolers Keep Engine Oil Temperature Under Control
      You may have seen Performance Engine Oil Coolers for sale on our website or elsewhere, and your first reaction may have been "who needs one of those? Not I." We can't say we blame you if your presumption is that either a) your engine is cooled by liquid antifreeze/coolant, so this thing can't be for you; or b) the word "performance" led you to conclude that hot-rodders are the primary target for these add-ons. In fact, if you tow a trailer, or tend to load up your SUV to the max, or drive at high speeds in very hot summer climes, you just might be the real target customer for an engine oil cooler. Allow us to provide some educational background on motor oil, and the critical roles (plural) it plays. Please read on!

    Amazing Turbo
    This product is amazing. It's made of good materials, no shaft play, I am pleased with my new turbo. I've noticed the difference in sound and power, especially when you floor acceleration pedal. Installation was easy. I would highly suggest this product to anyone who is considering it.
