Ordered a part from Improved Racing, it arrived quickly and was the lowest price I could find on the web. Very happy, and I look forward to ordering from them again.

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 could not fault these guys, either for their excellent baffled sump, nor their service. Well done.

I purchased the oil baffle and complete oil pan for an engine swap. Everything shipped right away, and the oil baffle fits perfectly. Improved Racing provides great products at good prices, and take care of their customers.

I have purchased several items from Improved Racing over the past couple months. Each purchase has arrived in brand new condition, packaged well, and in a timely manner. They have earned my business for any parts that I need in the future. -Austin

I have their FD RX-7 suspension toe/trailing arms and internally thermostatically controlled billet LSx oil cooler adapter on my car. Great products.
