IMO, that scoop is too small for the hood.

Yeah, it looks small to me as well, probally too small to offer any practical application other than aesthetic, unless the guy's plumbed his intake to it instead of out the front.

It is also probally worth noting that the 3rd. and 4th. gens.' scoops are somewhat w-i-d-e-r than the one pictured.

Bigger is always better, no matter what others may say.

Understood, but I don't see where I was ever prejudice. I offered some facts and an opinion. That was all. You stated my facts were wrong and tried to claim things that defy reasoning. I corrected you and you have been going off ever since. I'm sorry I wasted your time trying to help you with your misunderstandings. :pat:

I love the look of a good scoop on the 4Runners also. I am planning on making mine from fiberglass or metal and use my existing hood, though. The only thing I don't like is the checker pattern of carbon fiber. It will probably never appeal to me, but that's what makes us all unique. I still don't buy that you will get much noticeable weight reduction from switching over. That hood can't weigh but 30-40 lbs. as is, so at most you will only get a 20-30lbs. weight reduction... but I could be off on my numbers a bit. When I was racing SCCA, the guys that would race Miata's (some of the lightest out there) still worried about putting just enough fuel in for their run before worrying about carbon fiber anything. This was after they had the whole car stripped down to almost nothing. All I am saying, is even with those guys who are probably the most serious about weight reduction didn't worry about the hood. So don't let that be a deciding factor. Get the carbon fiber because you like the looks or just get a regular scoop.

I mean no harm by anything I say. Everyone is being honest so I might as well be too. The fact that reading something and not verbally hearing it can lead to a lot of misconceptions of how to take the remark or comment. I greatly appreciate both of your opinions and your support 94x4

I hope you guys can throw me some more information in later problems I may have or questions I might need. Yes, there is a gawdly amount on knowledge about Toyota's on this site. I'm glad I found it.
Take what people say in here as advise, not criticism. I was very backwards in many comprehensions of things as well, until other corrected me. No hard feelings. It just gets aggravating when someone starts hounding me like 94x4 did when I offer advice. I was never trying to discourage you from doing it, just letting you know that I didn't like the carbon fiber look and that some rationalizing about what to expect from a hood scoop was on the wrong path. I would hate to see someone get any mod for their truck for a reason that doesn't stand true as I don't think anyone in here enjoys throwing away money. But if anyone in here does... GIVE ME A SHOUT!

This thread reminds me of the “speed holes” Homer Simpson put into his car.

I can say with utmost certainty that USDM 3rd gens never had functional scoops. I am pretty sure the same goes for 4th gens. Only a handful of peeps ever made them actually "open" and I have no idea about their real world results, if any.

I can tell you this, if I had a functional scoop on my rig right now, it would be completely pointless thanks to my bug shield.

I agree with this. As an addition, though, I'd be willing to say there may be a way to plumb the scoop to the airbox with enough money and creativity. However, it more than likely wouldn't be worth it over cutting the bottom out of the box:

No sarcasm or anything intended Churnd, but why on earth did you cut the entire bottom of your air box out??

Poor man's FIPK. I ran it for 3 years with zero problems. Read my writeups before trying it though.

Check on the "3 years with zero problems", but surely you realize that there's a reason why all manufacturers plumb the air intakes to the outside of the engine compartment, i.e., cooler, fresh air?

But also less... so it's like a trade-off. Most of the time you're getting more air that's cooler too since you're moving. The only time it hurts is when you sitting there idling in stop and go traffic. No different than the $200 FIPK kit K&N sells.

O'kay, but I'd still try to plumb the bottom of your air filter box to the outsuide somehow just to get it away from sucking in the heated engine compartment air.
Also, for what it's worth, all I did was the ISR mod with the straight intake tube.

I wanted to, but couldn't find an acceptable place to route any kinda plumbing. It would have had to come from the front, and that wouldn't have worked unless I cut through the wheelwell fender. That would have been too succeptable to damage, so I scratched the idea. I wanted as much air as possible, and I didn't think I'd be able to route the size plumbing I wanted without having to do serious fab work.

How about ducting it to the lower valance under the bumper?

There is something like a grill structure down there that you could easily mount a funnel behind as the intake.

hell yeah jason. no reason to explain why youre putting a mod on your truck. its like some people jumped all over it cuz they think its stupid.

theres lots of mods people do that really dont make sense and some others think theyre stupid. let everyone do what they want to their rig. cuz in the end, whos paying for it? if you dont like it, dont do it to your tuck. enough said. put the lid on this can of worms, and go get you a hood with a scoop that you like, and ill help you put it on bro.
