5th Gen Deckplate/Elbow Mod?

Hey, everybody:

Looking for some boosts to power/sound and MPGs... I have found some conflicting information on 5th gens and the deckplate and elbow mod... seems like it's more popular and useful on the 3rd gens and below.

Have you done either mod to your 5th gen and seen any appreciable gains? It looks like a pretty straightforward mod, but I don't want to do it if there's no gain in the end.

Thanks!

Can you provide more details or links to the "deckplate" & "Elbow" mods, they sound a lot like snake oil.

*Edit: So the Deckplate mod appears to be where people cut a hole in the airbox piping and used a boat deck plate to "seal" it when going off road during "normal" operations the deck lid was removed to allow more flow. I am going to say no, If Toyota could have made a noticable power increase by making the air intake less restrictive they would have.

Generally you won't boost power without reducing MPG's and decreasing reliability. There are not many "power" mods that I am aware of for the 5th gen 4runner aside from complete custom set ups that most would never do such as forced induction/NOS etc........CAI, Headers, Exhuast are not worth much unless you have seen dyno graphs not from the manufacture proving so. You can certainly change mufflers to get a more pronounced sound but it wont have much effect on power/mpg.

The best way to increase power is to push down on the skinny peddle. Also my 2 cents, dont cut a hole in your air intake or piping. The 4runner wont explode if you do but I don't believe for a minute that you would get more power out of the motor.

There's a guy in another thread that just had a dyno run completely stock. He is going to install an aftermarket CAI and run it again. I am looking forward to an actual real test. Do I think it will add any appreciable power outside of the margin of error? No, but I applaud anyone for actually testing something to get data instead of just offering an opinion from their butt dyno.

I agree and I'm curious as well. I was thinking about doing it myself when I get an intake. Yes I'm getting one regardless based on previous experience and sound.
 
Did the Deckplate mod on my Gen 3.. I do not think I would attempt in the Gen 5. I never did it in my FJ as well.
 
Hard to tell but unlikely to be good...

The stock CAI tune is across a wide margin of rpms and speeds and is tuned for mileage. I'd be somewhat surprised in this day and age of accurate flow modeling if someone with a hole cutter and a metal plate could make any realistic gains on a modern car that didn't have serious drawbacks in everyday use. You are more likely to just screw up what does work without getting any serious improvements.
 
I turned my air filter lid upside down once....
On a 1978 Chevy 350....
It went "WOOOOAAAAAAAAAAA" when I floored it....
That is all.

HA! I did that once on an '87 GMC 350. It made more of a hissing/sucking noise in the cabin. I turned it back over...
