Product Reviews

Bought this back in November 2014 for my 2006 GT Stang and just installed it. Wow what a difference. More power, shifts tighter (automatic) and was not that hard to install. Great bang for the $$$'s. Wish I had installed this many years ago.

Love the upgrades from Steeda. Someone answers the phone right away when you call, and the customer service is great.

Sure noticed a big bump in hp after installing this! Thank you so much Steeda!!

For only a few hours of work you cant beat the power this pack produces. The additional 40 plus horsepower really woke up my 4.6. The quality of the parts in this system is outstanding. The intake looks awesome in my engine compartment!!

The Power Pak was the first upgrade I have to my my stock '07 GT and I couldn't be happier, improved throttle response and better fuel mileage. Installed it all myself in a morning, only special tool needed is an impact to remove the damper as my car is an automatic. If you are the fence about this, just do it, you will not be disappointed!

Had this installed at a local speed shop, makes a world of difference, feels like driving a different car. My '06 feels like it wants to stand up when I hit the gas. Very happy with this set up!

best bang for my buck I was a bit frustrated with all of the competitors on the market but after installing just the intake and tuner it feels like a whole new car cant w8 to put the pullys on and start looking into other steeda parts
