CSF 20-Row Transmission Cooler Results – 2011-2014 F-150 & Raptor Installed the CSF 20-row trans cooler recently on my 2013 F-150 3. 5L Platinum and finally had a chance to put it to the test. Here are some before/after comparisons towing our travel trailer (5,641 lbs measured at CAT scale, 12,740 lbs combined): Highway / Mountain Grade (6% over Cascade Mountains): • Before: Temps would peak around 215°F • After: Temps peaked at 203°F • Normal cruising on a slight incline is now holding steady around 194°F Backing Trailer Up Steep Driveway (~1 mph, heavy load, low airflow): • Before: Would regularly hit 240°F by the top of the driveway • After: Only climbed to 217°F Takeaway: Didn’t expect such a big improvement at near-idle speeds, but the cooler really holds temps in check. A solid upgrade — I’m very happy with the results so far. Thank you Full Race!

I love the new sound, just a bit louder, definitely a hp increase, deeper tone! It was a great choice!!

Would buy again, I would offer advice on installing aftermarket cooling lines if requested.

All is good but - I'm still trying to get an answer from somone about the screw size used to secure this to the once offered plate for EFR turbo mounting.

Super fast shipping.

have a fully stock 2013 si with no other exhaust mods, sounds amazing. the difference is much more noticeable in person compared to the videos. really nice deep sound. drone is relatively loud at ~3200 but perfect everywhere else

I wrote the review in the 1st screen it took me to. Poor customer service. Slow response from Donny.

Thanks and great products!

Experience with Full-Race was good. Shipping was faster than expected, install was easy as can be. 2-3 hours for install. Part figment was more than perfect. Only reason I am not awarding 5 stars is performance. I was excepting better cooling from this setup especially for how much the kit costs. Expect to see 7-10 degrees cooler temps

Need more 2. 7L aftermarket parts. But love the quick ship and competitive pricing.

Thank you for all your help with the manifolds and coolant lines! Great product!

My experience went like this. . . SUPPRISED, IMPRESSED, AMAZED, AND PLEASED. 10 OF 10. Thank you FullRace! Keep it up!
