03 E53 BMW X5 M62 4.4i V8 - Cold air, Spaced, Exhaust, Dyno 302
Wow. One word to describe this product. Drive by wire (ECM MODULATED) throttle systems are awful. I miss the days of the cable and spring. The sluggish response is to be expected on today's vehicles. THIS KILLS THE PROBLEM. Feels like a real power gain (although it's smoke and mirrors) but 10 out of 10 amazing product BECAUSE OF THAT. EASY install plug and play. Feels like a 30 hp gain but it's just converting and amplifying the signal to the throttle computer. Awesome product.
Works as advertised!
I finally pulled the trigger & bought this afe booster for my 335i f30... there's a refund option so I figured why not... try it & return it... i tried it & im never returning it. This should be a 1st mod for most cars. Makes it more drivable, more fun, maybe the way the way the throttle should have been made. The price is high but it is worth it. No added power but it make u feel all the available power more instantaneous. Buy it cause u wont return it.
Goes now without delay
Installed in 10 minutes , easy few steps, most difficult was disconnecting the original plug from gas pedal, everything else was easy. I'm not a car repair guy at all so anyone can put this thing in. Works as advertised , much faster off the line then before. Feels like there is more horse power when pressing gas pedal, I know there isn't added HP but great improvement to the cars performance. Id buy again , I highly recommend , no hesitation , easily worth the cost.
