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.

Oil pan baffle and crank scraper I recently installed the LS3 Corvette oil pan kit with the Improved Racing oil pan baffle and crank scraper. I am impressed with the quality of the baffle and crank scrapper. They shipped the kit very quickly. I had to make a slight modification to one area of the scrapper to avoid interference on my engine but I simply followed the supplied directions.

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.

Great Experience This was the first time that I used Improved Racing and it was great! They had the most competitive price on the item that I purchased. The shipping was extremely fast, too. I will definitely use them again! I'm very happy with my purchase and with Improved Racing! Monique(Texas)

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.
