USELESS?

[shaikh]

Aa the title says and after watching the video does it mean having a cold air feed is useless? Spending 100s on these short ram etc?

What do u guys reckon?

For the M and pretty much any regular road car the air intake alone will make almost zero difference at all, though long arm intakes will allow the engine to ingest water, you don't want that.

[Nairnster]

Cant be much more difficult than sucking the air through the convoluted stock intake routing and resonator though?

[Krzys]

Even with the best routing you won't notice the difference, it's just a placebo as a single modification, can be made to make an effect but you'd probably need to go mad with mega engine rebuilds and boost.

So putting a cold air feed intake is more of a "show off" thingy i guess? Unless ur on turbo or some insane boost? This is what i could think of as that gtr is stock with only catback and is 225 bhp. So does that mean u need to have around 300+ bhp if u want to see any difference with that mod?

[Krzys]

For the M, yes.

Do you mean a Nissan GTR or other Skyline? They are much more than 225bhp stock. Turbo charged cars respond much better to breathing mods but would usually need a remap to make use of it.

I meant the skyline in the video and ye i found out that turbo charged cars can make the most of this mod thnx for the info bro

[Butcher]

That's a GTT in the video. About 280bhp stock at the flywheel. 2.5 single turbo, as opposed to the 2.6 twin-turbo GTR. And rear wheel drive. I had the same (albeit older generation) motor in my Stagea. The figure in the video could well be power at the wheels? Would probably be about right. 

 

And yeah, cold air feed will make pretty much no difference at all on a Civic. Certainly nothing noticeable. Same with filters and stuff like that. Even on turbos these things only produce marginal gains at best, and even then, as pointed out, can do more harm than good in some cases. Shiny new parts though.....sometimes it's hard to resist

For every 3.3 °C (5° F) rise in intake temperature, air density drops 1%. The hotter the air, the less fuel the computer injects to compensate for reduced oxygen

Hmmm does it mean that having an aftermarket air feed is a better option? If it can keep the tenperature low? Yet again the test there shows that it can make things worst or more or less have no effects.unless ur ready to lose one headlight
