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.

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.

Transmission thermostat is awesome. Service from Improved Racing was great. Quick delivery of a very high quality piece. I ordered a fluid thermostat with -6 fittings for a 10 sec bracket racer. It arrived in 2 days. After installation, my 60ft times, that had varied by 2 hundredths, now only vary by a few thousandths. Temp stays right at 165 as advertised.

Order Fulfilled Perfectly and Very Expedient Shipping I ordered the VCM OTR for the 2009 Pontiac G8. The contents of the box is not a one size fits all. What I mean is that the G8 has different mounting hardware than the Holden Commodore which is the Australian version of the car. I carefully read the instructions and reviewed the parts which were included. Everything matched up perfectly for a G8 install. Could not be happier with my purchase. I would for sure order from Improved Racing again.
