2011-2020 F150 3.5L EcoBoost SPD High Flow Turbo Exhaust Adapter ADPT35

Overall the product is pretty much as advertised. The adapters are nice quality and the oem parts that come with the install are truly Ford parts. It took me a few hours to install in my garage. I think this was a mistake to install them because I honestly can not feel any difference in power and have lost 1.5-2mpg with this install, and that is going to summer fuel when everyone typically sees an increase. I would be taking them off ASAP if it wasn't such a pain to do. Others may love it but in my opinion save the $250 (with install kit).

4hrs install due to limited clearance. The new 2017 3.5 ecoboost responds well, the turbos are Very responsive allowing the truck to shift into 10 gear earlier increasing fuel efficiency

Not the easiest items to install. The truck is a 2014 F150 4x4 with 63k miles on it, so that didn't help with the studs. The stud removal tool work on 3 of the 4 studs provided in the install kit with no problem. The remaining stud broke off above the round center of the stud. Had to hammer on a socket and heat the flange with an induction coil for 20 minutes. Then hit it with an air impact to remove it. Installing the all new parts was easy after that ordeal. You can hear the turbos more out the exhaust but the 4 diamond eye exhaust also helped. All I can say if you do this be ready for the worst case if your truck not brand new.

If you ever plan to put Downpipes on your ecoboost. Definitely recommend picking these up too. They're literally right there after the Downpipes are off. I put these on with catless Downpipes and a catback. Install was tricky. Driver side stud was very hard to get to and get out due to the way the factory turbo adapters are designed. Putting everything back together took about a quarter of the time. Start soaking the studs early. I hit mine everyday for a little over a week. All of them came out no problem on 55k mile northern truck. Lot more turbo noise and everything combined definitely gave me some more and I picked up about .8 on my gas mileage. Definitely something I'll be adding to future ecoboost trucks I buy!!

I really like the performance now after I put this and the 3in catless downpipes on, you literally feel the difference in power, only downside is the stud kit from the website is overpriced so I ended up buying all 4 studs, both gaskets and bolts directly from Ford for $30 cheaper, I love the sound and whislte. Highly recommend getting a stud extractor!!

Took 2-3 hours to install. The only downfall to this kit is the crappy stud remover tool. Overall it went well

Really enhances turbo noise and spool time is reduced

This will be the same review I posted for the SPD catted downpipes: Pipes are awesome. Sound great. Highly recommend getting the SPD turbo adapters and install kit while your downpipes are off. Exhaust whistle is much more noticeable, and tone is more grunty. I had clogged cats and needed to replace an O2 sensor so I did everything all at once. Quality is top-notch, install went okay. Had to use a Map/Pro torch to heat up the turbo housings to get two studs out (two studs turned out of the turbos when trying to loosen the downpipe nuts, two others stayed in). Jacob Hozen from SPD is awesome to deal with, if you have any issues, questions, or want to reach out for expedited shipping. Be sure to follow the simple 12-minute break-in procedure included in the instructions.

A must-have if you really want to clean up your Ecoboost's breathing. Opt for the full kit and install is no problem. While there are some horror stories on turbo studs; did mine at 60K along with the y-pipe with no heat & no issues at all. Hats off to SPD & Stage3 for quality performance parts & service.

These adapters do work they are indeed a bit of a pain to swap out. Truck is not tuned or dynoed but u can still tell ghe difference in sound and performance and for those of u wondering it still helps even with catless downpipes, i knw when i was ordering i was looking for more info besides stock gains hope this helps

If you are going to pull the turbo's it's an easy swap if not good luck! Great addition with the 3" downpipes letting it breath. The stud extractor also worked perfect with my impact gun, and also helped with the broken manifold studs that I had to replace.
