I should include that all this applies to a stock size MAF housing, increasing the housing size will DEFINITELY allow for the use of a larger intake tube.

Radiant + ambient but yeah, sounds like you did your homework and used instrumented tests so I can't argue that. And that's correct plastic doesn't reflect heat, I should have used the term ABSORB. I can't comment on the OEM FX intake because I've never used it and haven't read anything about it. The comparison is always aftermarket v. rev-up intake anyways so it's sort of irrelevant.

I think you're mistaking larger+shorter intake RUNNERS for intake tube however. As long as you aren't restricting flow pre-TB you simply aren't going to see gains by changing the diameter of the intake tube, the only thing that matters is volume and velocity across the throttle body, you can remove the filter and install a 12" intake tube but aren't going to see gains unless there was a restriction in the first place.
The FX intake is basically the same damn thing. A little longer, but the same. Aftermarket, rev-up, they're all junk and a waste of time.
Totally relevant. What works for the FX works for the G and the Z.

Bro, home slice, mi amigo, I think you're mistaken actual proven fact for poor information that's really really old. You don't believe me but hopefully others reading this do if they're interested in breathing new life (power) into their naturally aspirated VQ.

Nope, not mistaken anything for anything. I know exactly what I'm talking about.

Size is the restriction pre throttle body. No intake tube at all would be best if that were possible. Velocity is at work here instead as one needs an intake UNLESS going with i.t.b.'s.
Made power with the stock t.b. and made more with the 75mm.

The Admin and LMT intakes use a larger diameter MAF housing integrated as part of the intake yes?

Are you asking me a ? to which has an obvious answer regarding a comment you made about an obvious feature of any large diameter intake?

It's not that I don't appreciate the comments, I do. Here's where I think things get skewed.

99% of all comments (pulled those statistics straight from my butt) about intakes and how they don't increase power or even LOSE power are directed at bolt-on intakes that use the existing MAF housing.

LMT and Admin tuning intakes aren't an accurate comparison because they include a high flowing MAF housing, they are NOT a direct bolt-on replacement, they REQUIRE tuning for the larger MAF housing even though they can reuse the existing MAF sensor. They make power because they are actually fixing a restrictive point in the intake.

I'll go ahead and say YES it's disingenuous to claim that no intake can make substantial gains on this motor, in the future I'll be sure to specify that a BOLT-ON intake will not make measurable gains in WHP. I'd love to see dyno results of either of those intakes as the ONLY aftermarket upgrade to see what they actually make on a stock (tuned, since the intake requires a tune anyways) motor.

I'll also give you a few thanks on your posts here since I do love a good discussion.

Definitely with Gary on this one, one of the first things I did to my G was take the cats off and weld the heat shields in 4 places on the top and bottom of each cat. Sure the SS clamps would work but it's a little janky for my tastes.

No, I'm not asking for thanks, but thanks anyways. It's nice to get some acknowledgement when one takes a minute + to share good information, not particularly on this thread. People are a little more greateful on the FX and Z forums, that's all but I post anyways as it's sites like this that I've learned so much from, so I'll give back.

1st, I don't recall "BOLT-ON", or whether or not said intake would or would not be a "BOLT-ON" intake being part of this conversation and 2nd, what larger diameter or "Large Bore" intake is there that does not have a larger MAF housing? I know of none.

Now, one could certainly make more power within the confines of a stock-sized MAF housing. Get rid of the silly slinky-like rubber connectors that disturbs the air (turbulence) as it passes through the intake, use a 3" pipe with as few bends as possible and importantly as short as possible, insulate said pipe, get the largest open element air filter with a velocity stack, replace the throttle body with a 75mm and make an air box to seal the filter from the bay. Everything I did minus my diy 4" pipe + tune. I'm not sure how much more power one will make but I know for a fact it will make more and probably enough to be noticeable as it will make it easier for the engine to draw in air, period. That's what it's all about.

After I installed & tuned my diy 4" intake, I extended it approx. 1 1/2 feet with the 90* piece you see below in order to get the filter as far out of the bay as possible, simplifying my soon-to-be air box. That extra 1 1/2 feel and 90* bend KILLED performance. At that time, my 0-60 went from 5.6 seconds to 6.8, negating all the gains from the 4" and then some. Shorter straighter intakes make more power all day long. OEM, stillen, etc. are no good.

If paying more $ or working harder (assuming you're the one doing the welding) to weld heat shields floats your boat, it's all good. I've got hose clamps in my pond that have been there for over a decade connecting a hose to the pond pump which I service a few times a year and they're in perfect functioning condition with 0 rust. I'll take that option all day long. Drop your welded heat shield in water and lets see how long it lasts.

It's not a competition to see "who wins", and I've been off at the Ford dealership in town buying my grandma a 2013 Ford Escape so I haven't had time to play on the internet :P

In all seriousness though the Admin tuning intake is an excellent piece when coupled with a 75mm TB and all those other mods you have. If I ever decide to make my G anything other than a highway daily commuter I would definitely be looking at one.

I'm less of a LMT fan simply because of their FB page and how they almost encourage reckless driving on public roadways. That's an entirely different discussion which I'll happily engage in lol.

I like LMT's size but not the bends though this one's got the best chance of sealing the filter from the bay. I like Admin's straight pipe and I'm a fan of the owner. I like mine the best for obvious reasons.
