Great product great customer service. Bought this thermostat for a 600+hp 335i and it regulates temperature to a T. The car never had a oil cooler before and even now with 2x 20row coolers the car warms up just as quick. The straight through design is genius and hasn't let up once on track days or everyday on the street . Very happy with this product and have recommended it to anyone in the market for one.

Very professional service. I recently ordered an oil thermostat and oil cooler. I was a little skeptical of what I may receive based on the very keen pricing. I was very satisfied with both the product quality and the packaging. A check sheet was included which showed there was careful completion of my order and the freight costs were reasonable to Australia. I will definitely recommend this supplier to colleagues.

transmission cooler thermostat. So far the thermostat is working great, I chose Improved Racing's because of the AN fittings. I had tried a cooler with a built in bypass but it wasn't effective during cold weather. I installed Improved Racing's 145 degree stat with a tube and fin cooler and it's working great. I installed this on a 2007 VW Beetle equipped with the notorius 09G transmission. It's got new life now.

Will definitely buy here again I ended up in a pickle and needed a replacement oil cooler asap. The company that made my original piece had folded, so I started looking around for a new vendor. Via interwebs I found Improved Racing and their prices and inventory were suitable for my needs. I ordered the bits I required and had them in my hands even quicker than expected. A flawless experience. I will definitely buy from them again and have already recommended to auto enthusiast friends.

I am very happy and impressed! I am impressed! Very nicely made oil cooler adaptor. Machining is gorgeous as well as you anodizing. I love all the products you sell. Presentation, quality and design are outstanding. One stop shop for all my oil cooler needs. This is where I will shop hands down! Thank you for making these parts and including the killswitch tag! I don't put any decals on my car mainly not to advertise but IMPROVEDDDD is on my side window :) Looks great on my 2015 1LE
