i know Gadget has posted that in a 3.4 on the dyno the 4runner with the FIPK lost power vs. 5hp for the air box mod. I know the FIPK looks and sounds good, but is 250 bucks worth it???

 

do a search for "airaid mit" and do the deckplate mode super cost effective

 

I used a cheep cone filter off ebay for $40 and I think it is every bit as good as the K&N FIPK for flow but at a fraction of the cost.

 

I was pricing FIPKs until I did a bit of research here . Since then I've put a 4" deckplate in my '04 Taco, and removed the elbow from the wifes' 4runner. Both mods provided acceleration gains you can feel. The deckplate mod is just louder. Still testing gas mileage. I have gone from aftermarket (K&N, Amsoil) back to OEM air filters since reading the "deisel" tests. Thanks Yotatech!

 

I put on a K&N FIPK this weekend. Prior to install, I did a crude test for perfomance gain. I'd like to hear comments on my test. I have a five speed 3.4L Taco so those with automatics can't do this one.

Elapsed time from zero to 70 mph starting (from dead stop) in third gear. It takes about a second and a half to get the clutch completely engaged.

Before the FIPK, 17 seconds....after, 13.

I thought this test would be good because it gives me a relatively large block of time and the full power band.

Any comments?

 

You're saying you lost 4 seconds by installing a K&N? Sorry bro, but no way. That's a good way to burn a few thousand miles off your clutch though. Yikes!

A better method is to put the cruise on in 3rd gear and do a 30-70 run at WOT. All you have to do is slam the gas down and start and stop a stopwatch. Do it three times in each direction (on a deserted road) and then get the average.

Don't waste your time though. If anything, you have lost HP with that mod.

 

Could be a way....I have no idea how much air was getting through the stock filter...it was well used.

I was hoping somebody would give the test a try and tell me what kind of numbers they're getting.

 

cut it out....for all you 1st gen owners heres an intake mod for all of us



in that hole is a k&n drop in and you can drill out hte bottom...i was going to but i dont want to drill it out without having a spare airbox so as of now mine is solid on the bottom.


and just for ˟˟˟˟s and giggles while were taking about air heres a pic of my intake manifold....isnt it clean and beautiful?

 

I also made my own aloy heat shield that is 100X better that the fitpak. Check it out:

 

Would the elbow mod make any difference on my 2.4 22re? The k/n drop in didn't seem to make much of a difference.

I'd be scared to drill a hole, i do alot of mudding and the winters are pretty wet here.

 

Yea, I threw away $50 on the drop in myself. Didn't notice ANYTHING. The $15 cone filter is the way to go. I have much beter throtle response now plus it sounds cool.

 

I did the FIPK, and it sounds cool at full throttle. When I'm at idle, it does make a lot of noise that's very close to an old belt, but mine are fine. Anyone else have this problem or has anyone else had this problem in the past? What did you do to fix it?

 

The FIPK is the way to go. Yes, it cost more but it is well worth it. Especially if you have LC Engineering header, LC Engineering high flow cat, LC Engineering big bore throttle body, LC Engineering Mild Cam, and Flowmaster split exhaust. The FIPK with the other mods really kicks ass and makes a lot more top end power which is awesome. I can chirp in 2nd without even trying.

 

deckplate and isr mod here.

faster acceleration and awesome sounding for less than $20.

 

with this Deckplate deal and even the lame K&N FIPK heatshield, why would you open you filter up to hot underhood air?

 

I just used General Purpose Flat Black spray paint from AutoZone. Brite Touch Brand.

 

Don't Be A Cheap Azz Ghetto Modding Your 4r! Get The Fipk!

 

Don't cut holes in the box. No reason too. By removing the elbow you get the same results. If you do it right you can pop the elbow back in or out when ever you want to. I also screend the elbow hole on the inside of the box to keep out little critters. With the lip on the outside of the box I just trimed down my elbow until I could snap it in or out.

 

Don't do the FIPK. I did that on my 93, and it made no difference. Wish I would have just done a K&N drop in and save a lot of money.

 

Probably a stupid question, but: I have an 87 4Runner, and since I want to get EVERYTHING out of it I can, I was wondering if I could do something like this deckplate mod to my airbox. Like cut a round hole in the bottom of my airbox, similar to the deckplate mod. I have a drop-in K&N in now, but would doing something like that have any effect at all? Say maybe with a screen over it to keep the big chunks out...?
