Let customers speak for us
Installed this SPELAB thermal bypass valve alongside a deep pan upgrade and the setup works flawlessly. Trans fluid temps drop fast and stay right where they should be.
The overall fit was great and the build quality feels solid. I noticed a past review complaining about the O-rings being the wrong size—just wanted to clarify that those O-rings aren't for the bypass block itself; they are meant for the metal threaded filter adapter. Don't let that review throw you off. Solid 5 stars!
Surprisingly fast shipping and decent quality with half of big brands price... will come back!
fits well, would be better with instruction.
love this red! Customer support is also very helpful. Hope it will last.
Love it! Fits my 2017 F250.
The fitment was fantastic And it went together really well and fast
Great shipping. Great product. Was easy to install even though I had to cut some pipe off but overall happy with product
Solid intake manifold, no fitment issues.
Fit perfect and was of high quality material I have had the plate on my truck for about 2 weeks now and it is working great thanks SPELAB
The cold air intake was easy and fast to install. it looks great and boosted my truck up a little for performance without breaking the bank. it’s the best bang for your buck even if your truck is stock or built it’s worth the money
hard parts are amazing and everything went together great
Install was easy and straightforward. Everything lined up nice. Peace of mind knowing there are no worries about potential destroying my engine, due to a nut.
Highly recommend for 2009-14 F150 4x4 3.5 ecobeast!
Installed myself at home took a little over a week for everything to show up, install went tough but that was the trucks fault parts were all good and the tunes run smooth, getting a little over 2 mpg average better fuel economy definitely worth the money.
Made my truck run much better without having to worry about the grid heater bolt falling down in cylinder 6
