Datalogging several days doesn't equate to much if there is no SOP, especially when trying to prove out that WAIs are beneficial over stock.


There is no reason an intake sitting inside the engine bay makes power over stock boxes (let's say with K&N panel filters so we don't start arguing over flow)
And when I say no reason, I mean NO REASON. The stock boxes pull in outside side through the radiator support. SRIs, ESPECIALLY non shielded ones EXCLUSIVELY pull warm to hot air that has either flowed through the 180 degree radiator and/or has been heated by the engine.

Short rams on this platform are worse than stock in every measurable way except sound and aesthetics. A hood-closed dyno run with one would most likely show less power than stock. Even if it's free, it's overpriced.

Getting back to OP, I paid a little extra for the nismo CAI. Love the powder coated look and there is no cutting involved on install. They also have the air bypass valves that prevent hydro lock if you happen to pick up water. Kit comes with everything you need to replace the washer fluid reservoir. I'm happy with it!

mike has never been on a dyno. his gains are purely speculative. ebay intakes only serve to demean a 40k dollar car.

Anyone that has actually worked in the engine bay would know which intakes work and which ones don't

Cobb Accessport with some maps "plug and play"

But if that's the case I personally would leave the stock intakes alone(or if anything put drop ins) and then change the exhaust and cats.

I'm sorry guys this is my first foreign hot rod. Always had modified Mustangs. I feel like an idiot But what is a drop in. I know the formula in Mustangs more fuel more air. Never did a Japanese vehicle. I would assume it's all the same.

A higher flow panel filter (e.g., K&N) that "drops in" the airbox like an OEM panel filter.

Noob question, but do I need to disconnect the battery when putting in Drop-In K&N filters? I wasn't sure if the increased air-flow from the K&N's was enough to need to reset the ECU.

Guys sorry i'm a bit new, i'm thinking of installing the stillen gen 3 CAI too, but do they affect me at lower rpms when i floor it from a stop? Driving a 7AT 09 370z.

I'm gonna install the r1 titan powerhouse amuse exhaust soon too, would they be a good combi of any sort? And after both gets installed will i lose a lot of my low end and pick up slow?

I swapped out my factory intake to a Takeda CAI long tube and the instructions asked to disconnect the battery. I did not see a purpose for this and I have had no issues, might just be a worst case scenario to avoid lawsuits. Can't see a reason why you would need to mess with the battery to change the air filters.

I ended up throwing on the K&N Drop-Ins without doing anything with the battery. Been in for a couple weeks now with no issues (knock on wood).

Has anyone tried the jwt dual pop with the mishimoto silicone hoses? I've got the K&N drop ins now and am thinking of this combo, not sure if they'll work together.

[KMO-II]

Long tube or standard? Which is the best brand that you know of, and what are you currently using. After install did you have any noticeable gains? Also whats average pricing? I've seen from $399 - $750.. Tks for any and all suggestions.
