Dorman vs FRPP intake 0-60 videos

I bought my 02 GT with a Dorman intake already installed. It always had a "gritty" feel to it during normal acceleration. It has also been underwhelming in terms of acceleration. I have talked about it in a couple threads here.

I have read that the Dorman intake is very restrictive compared to the FRPP intake, and that is is responsible for a loss in HP and TQ (up to 20HP/20TQ)

I finally got around to getting a brand new FRPP intake and replacing the (still functional) Dorman one to regain some of my lost preformance.

Here is a video of the before and after on the same stretch of road, in similar weather conditions. nothing was changed except the intake (and gaskets).

The FRPP intake got rid of the "gritty" feeling and sounds a little throatier, but my resulting 0-60 time is relatively unchanged at a measly 7.5 seconds.

It sounds better in the second video.

So was it worth it to swap out the Dorman for the FRPP.

Less thinking for the PCM?... IDK, just seems like the logical thing to do for a speed run.

Worth it for me?....yes. The gritty, grindy, vibration feel at take-off always had me concerned. I had been chasing that "problem" since I got the car. It gives me peace of mind to have it smoothed out.... not to mention that I got the intake for $100 by using some Discover rewards points on Amazon, and I did all the work myself, so it was a relatively cheap swap.

Worth it for someone else?.....maybe. If your going to leave the car mostly stock, it seems that the Dorman is comparable to the PI intake as far as performance goes, but it's not as smooth. I find this fact puzzling, since my Dorman intake was NPI.

Awesome!
Like I said, you can hear a difference in the vid. I'll bet there is a small performance gain as well... You'll just need some timing equipment to actually see it.

There may very well be some improvement on a dyno, but a simple 0-60 doesn't show it time wise.

overall, Im happy that I did the swap. that gritty feeling has been driving me nuts. $100 for it to disappear was well worth it for me. I just wish I could have picked up some better acceleration from the swap...especially after seeing all the Youtubes of (supposedly) stock Edge mustangs doing 0-60 in 5.5 seconds.

0-60 times on a basically stock GT isn't really going to change. It'll be more in a 1/4 time and will show up more when you do more mods. Also going to make a tune more effective.

Im sure you are right. However 7.5 sec 0-60 is just pathetic..... these cars, in stock trim, are claimed to be 6 sec 0-60. I dont know why mine is so slow. It runs great otherwise.
