All parts arrived promptly and packed well. Installation was smooth and trouble free except for the tube style heater which would not thread into the new intake elbow. The provided plug threaded in fine so will have to revisit that issue before winter.

Overall I was very impressed. Pricing was great, everything I needed was provided. Quality of the parts was good. I would definitely recommend this package when compared to others.

Great products! Works perfectly!
Thank you so much!!

No written instructions came with the kit, no big deal. You will definately need the IAT extension wiring harness, which we wasnt told we needed. I ended up making my own extension but if you don't the truck will not start. Also the intake horn doesn't fit straight onto the inlet tube so if it looks crooked just make sure the clamp is tightened.

Packaging was good, install was simple, and it sounds great. What more could you ask for?

Kit went on fantastic, all hangers lined up. Freed up power and MPG. I installed the SPELAB muffler too, good combo, good sound. It drones under load and at about 70 but not unbearable. Super happy.

Have purchased a few different things , all worked at advertised! Will be making future purchases.

Great finish, not a terrible install, just time consuming. Just take your time it, we’ll worth it!

I took my F 150 to a local mechanic to get the differential cover and gasket removed, the fluid drained and then everything put back together. I didn't want to bother. My mistake. I got the truck back, put a piece of cardboard under the rear differential and determined that it was leaking slowly. I went back to the mechanic, they supposedly fixed it, but the cardboard check failed again. I went back to the mechanic and they told me it was the pinion seal bearing that was leaking. This problem never existed until I had taken the truck to them. I got the truck back in the pinion seal was no longer leaking but I still had a slow leak from the gasket around the differential cover. $400 later in three trips back to the mechanic I gave up, bought the SPELAB cast aluminum cover and the lube locker gasket plus the necessary fluid and did it myself. No leaks since then. I particularly like the little sight glass since I was able to get the fluid exactly to the halfway mark within the sight glass. I should never have gone to the local mechanic in the first place.

Very well made with quality materials and hardware! You will not be disappointed.

SPE ccv reroute is the best bang for your buck and works very well. Easy install and looks great when installed.

This 5” downpipe back kit fit absolutely perfect. Could not ask for a better fit and finish of this kit. All the hangers are in the correct location and the clamps supplied are of quality!

Installation was a breeze!

I bought this kit for my 2019 Ford F350, the same kit I bought for my 2014 F250 almost 5 years ago. The first kit I had significantly boosted my power to pull my 5th wheel up I-17.
While I haven’t pulled anything big yet with my F350 I can already feel the difference in power and performance.
VERY happy with my purchase and…no more DEF (garbage!).

Great replacement cover! Looks great and was easy to install and makes it much easier and cleaner to change my differential gear oil!
