I'm not excited about this product. There is no power increase, unless you lock tite the bolts for the throttle linkage they will move. I think it's not worth the money.

Have seen a major increase on Fuel mileage and notice a little bit more torque. I have 01 f150 4.6 and it has been the best aftermarket add-on for the price. It has helped with towing.

good overall. helps. with low end power. towing and stop light starts are noticeable improvements. The claim to improved gas mileage is not happening. This is the third unit in three different vehicles with the same results, large low end torque improvements with gas mileage staying the same. Worth the money and time.

I installed this along wih a spectre cold air intake. It took me around 2-2 1/2 hours to install both but I would have to say it would have only taken about 1 hour at most for just the TBS by itself. It works great! I hear it wistle all the time, The kit had everything I needed and it instantly gave me a boost in power and acceleration. Very happy with my choice and the great price and savings I got on it.

I have been thinkin about putting one of these on my truck for awhile now and have been doing my research to find out wich brand to go with as well as best price. To start i could not find it any cheaper then here on autoanything. After finding it here and deciding to go with the poweraid tbs after reviews saying this is the best way to go i ordred it. It came in the mail right when it was supposed to no delays at all. Installation was a breeze. I installed it in the parking lot at work in about a half hour during my lunch break. Super easy! Everything fit perfectly and looks great. Performance wise its great i have gotten about 4 more mpg with it installed and throttle response has definetly improved especially on the freeway. I did not notice a great horsepower diffrence but the mpg and throttle response are definetly worth it. Next step for me is a cold air intake then i believe i should see the horse power difference. The whistle sound the tbs makes is great too. I do notice it from time to time from the cab but i actually kinda like it! Cant tell you how many times ive been asked if my truck is turbo charged! All in all its a great product and i would definetly reccomend this to anyone lookin to add a lil extra performance.

I rated the throttle body quality low just due to the fact that the 4 bolts included with the kit are the same length as the ones that are removed. The installation would have been less than 30 minutes had I not had to go purchase 4 longer bolts. What a pain since I had my transportation torn apart. I haven't run through a tank of gas yet, but I think I'm getting better mileage. Time will tell. There seems to be a nice improvement in low end performance and the noise is not very noticeable. At this point I'm glad I purchased it and will install on my wife's vehicle when I verify the mileage improvement.

One hour to install. A nice complete, everything you need, package. Too soon to tell for performance and mileage improvements.
