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

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.

Excellent Products, Fast Shipping This is one of a few vendors of automotive parts (Fore, Radium, Science of Speed also come to mind) who sell unique, high-quality parts and has a fantastic staff to back them up. I had a problem with a couple of orders placed back to back because I was in a hurry and ordered the wrong things. They fixed them both, combined them to save shipping charges, and shipped everything that same day. I have bought a handful of things from Improved Racing and they are always well packaged, well documented, and look fantastic.

Quality, second to none I've been running Improved Racing's road racing trap door oil pan baffle for 6 years now, and most recently their thermostat oil cooler adapter. The quality, precision, and customer support is second to none. Their products have help protect my engine through years and years of extreme abuse. Affordable prices for quality parts, backed by great people.

No BS just quality parts shipped on time Im currently swapping an LS3 into a 93 Rx7. Ive spent over 30 thousand dollars in 2 weeks. Improved Racin was the ONLY business that promptly shipped my parts, didn't screw up the order, or had some screwup holding up my project. Extremely satisfied.
