AEM Cold Air Intake Review

AEM Cold Air Intake Review
Hey GSF fam, finished installing:
AEM Induction Cold Air Intake Kit 21-780C
Designed for RC-F but fits our GS-F. Carbon fiber cover needed holes slightly enlarged to fit properly, and small trimming on fender side.
Construction is good, fit and finish spot on, and uses OEM cold air intake inlet from factory setup. This was my major deciding factor compared to others. Your choice to recirculate crank vents or block them off.
N/A mods are trivial, and whatever HP is gained or lost I would not know. Sounds stock on start up, idle, and sub 4k rpm. Daily driving is as quiet as stock, WOT sounds more aggressive as expected, but nothing crazy.
For what it costs I think it's the best choice compared to fancy pipe only swaps, or half airbox and pipe setups.
I will post more impressions after living with it for a while.
Monty.
Reused OEM cold air intake duct.
No mechanical skill needed for this install. Straight forward 👍
Some HP..

Well Steve, it's just like our Supra world, unless we do back to back dyno testing, we will never know for certain. For me, I like the price, fit, finish, and dyno sheet provided by AEM. RR have their own products to sell, their own statements to make. Their fit and finish is as described by others on this forum. I absolutely refuse to pay $600 for a carbon fiber pipe, or a bit less for titanium.

It looks like AEM has one in stock and we can beat Summit's price.

This intake definitely has more surface area than the factory flat filter and it providing cooler air since the intake flap that opens into the hot engine bay is removed. I could see where there could be a possible gain of a few horses.

Why was there a secondary air intake flap in the first place?
Isn't that part of limiting intake for the Variable Valve Timing System?
If the air intake is disrupted by removing the flap, doesn't that affect the way the engine works?
I remember after fitting my Takeda system, the mechanic forgot to close the secondary flap before installing the filter element, and that causes the flap to remain stuck open as it was hitting the filter element head. That made the car sound great at the low end, but I definitely lost low-end power.
