FinishLine Racing School uses DEI products on several of our cars. With the extreme temps and humidity here in Florida, DEI thermal products keep our cars cool! And the Radiator Relief is by far the best we've used in reducing problems caused by high operating temperatures as it also extends engine life which is imperative to everyone in the racing industry!

"At higher elevations my car has a harder time getting a denser air charge. With CryO2 it runs as if I'm at sea-level even though I'm at 4,000 feet. I just wish I had more trunk space for additional tanks, I would never shut it off!"
Bert Stanton

"This year I installed the CryO2 system on my 97 Turbo Acura Integra. I had never broken 13.5 mark in the 1/4 mile yet in my very first pass with the CryO2 system I pulled a 13.12 - I'm sold!"
Joshua Davis

"Admittedly, I was skeptical at first when I purchased Radiator Relief. After just a single treatment I can say it works exactly as claimed, and with no ill side effects."
Bruce Duncan

"With gas prices on the rise I can't afford not to run DEI's Radiator Relief. I need my truck to warm up as soon as possible and thanks to DEI it does !"

"Aussie Customers have really been raving about the results of the CryO2 system. Not only is the system producing imporoved results but Subaru STi owners and customers of Quantum Racing Industries in Australia on average make 33HP at the wheels with a complete CryO2 setup. Now thats the Power of Cool !"

About a month ago I installed DEI's CryO2 System on my Subura WRX Sti. Thanks to DEI's awesome instructions manual I had it firing liquid cold co2 the same afternoon I purchased it! Now I can spray a cool shot of co2 for performance and then purge clouds high into the air during my shows - DEI for life!

"We all knew that Project Bella was going to be hot but now thanks to Xplosive Performance and the continued product support from DEI we've utilized the CryO2 system which has provided us with the cold, dense air the 240sx needed to run not only faster, but quicker quarter mile times in the Florida heat!"

Supra's get hot, especially after some high pressure boosting. DEI products keep it cold and protects everything that the heat soak could potentially affect thanks to the wide array of thermal heat deflecting and insulating materials. Don't think I forgot "The Power of Cool" - how else could I drop my overall intake temperature 50°F without using the Cryogenic Air Intake and Intercooler Sprayer?

Fidanza Engineering is known for upgrading our company show cars with products that stand behind their performance gains.  We quickly realized this after installing the DEI CryO2 system on the twin turbo Corvette and didn't stop there! Now the supercharged 350z and Evo 9 are CryO2 equipped because the quality and performance behind DEI products speak for themselves.
