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.

Great company and product! First of all, Improved Racing has a great customer outreach and response team. When I told them USPS had delivered my package to the wrong address, they immediately let me know they could rush out another order if necessary. Luckily my package was delivered correctly a few days later, so a repeat wasn't necessary. As for the hardware I ordered, I'm very impressed with fit and finish. I wasn't even sure there was a way to adapt my Aeromotive FPR to normal rubber EFI hose, but IR had the correct (weird) adapters! They're -6 ORB to 3/8" barb hose fittings. The 90 degree fitting with full swivel is a very nice piece and fits exactly where I needed it to, with flexibility to spare. Thanks again to Michael and the Improved Racing team!

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.

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

Simply Wow I've ordered all kinds of automotive stuff from many different vendors over the years, and was blown away by Improved Racing. The items I needed were well engineered, complete systems (no chasing down small items that aren't included) and very well priced. Not only that, but the shipping was very reasonable and extremely fast for the cost. I will be ordering from them again.
