My TOB was squeeling more often then not, so I had it replaced. 2rh job.
The heat exchanger is outstanding for those hot days of cruising. I could feel the car getting slower from heat soak after 1 hr of spirited driving... now it doesn't lose much power at all. We have yet to see a really hot day here, but i'm sure it will be as effective.
Best $400 to spend, specially if you have a pullied car. You can't forget to upgrade your cooling system when you add those pullies. They have fans and a protective screen as options. I'm sure the "COBRA" painted option adds at least 27hp to the wheels LOL.
These cars run hot in stock form... I can't imagine upping the power level to a 2.80 or 2.93 and trying to nail down a tune in a cooldown state, then go out and heatsoak the car and throw the tune out of whack.
They have a comparison spec sheet on their website of all the contenders to save alot of running around to find the best one. Just look at the specs and see for yourself.
