i have paceset tlongtubes, magnaflow cats ,1.7HS , fastman ,edelbrock airgap,sct tuner and 14x3 autolight 3923. right now it seems like my truck has some balls for a 4x4. sc/sbWhat you get & how you use your truck will decide if its worth it
Original FIPK from K&N back in the 90s was a 14x2.25"
Installed one late spring 96 on my new Indy.
Noticeable gain off the line & in top end power.
July 96 went to the dragstrip for my first time (Chrysler @ Cayuga)
Raced against 2 other identical Indys a bunch of times
Only things I had different was the K&N 14x2.25" & a matching f/g tonneau (125lbs more wt)
I pulled away from both of them off the line & all the way to the finish line every time.
Least I beat them both by was .25 seconds.
That was about 3 truck lengths at the finish line.
Going to a 3" tall K&N many years later noticed even further gain.
By the time I returned to the track I had made other changes so cant say how much it improved ets.
Paper or other manufacturers filters do not give the same results :nono
Link below lists various bolt on mods & what the et reduction was for my 96.
Dude. Gears. If you are running 33"+ tires do the gears!my question is how would my truck feel if i took out the 3.55 with the open rear. and put in 4.10 with a lsd ? i just dunno if that 2300 dollar price tag to do both front and back +labor would be worth it. or should i continue with the motor . heads/cam ?
