Injen CAI and fuel consumption

**hugohung23** · 18-02-2008 08:36 PM

Did a search for Injen CAI and fuel consumtion but it didnt return anything so hope this hasnt been covered.

Recently installed my CAI and me and my brother totally killed it hitting vtec 9 times and have been since driving it pretty hard.

But get this, my fuel consumption is 100km/9.6

The best i ever got before i had the CAI was 100km/9.29, and that was NO vtecing and basically driving like a grandma mostly arnd 2500rpm.

Anyone else have these sort of returns for fuel consumption after filter installation? cos thats totally awesome.

I base my figures on the below calculations:

Before CAI installation

520km from 48L

= 100km/9.29L

After CAI installation and totally thrashing it:

326km from 31.28L

=100km/9.6L

As a test, I'll drive really really conservatively and see what sort of returns i get.

Im struggling to comprehend how much of a difference an intake can make, its unbeleivable.

You think if i get an exhaust system fuel consumption will be even btter?

Ok you've sold me. I'm going to invest

I had a similar impact (initially) with the K&N Typhoon intake (not a CAI)... couldn't explain it either. But then my driving style morphed and I moved to the city >_>

Driving a type R -> No need to worry about fuel economy mate.

If you after fuel economy go for Jazz or Yaris.

wasnt really in it for the fuel economy, but dam, its a bonus, it means more vtec for me hehe

**Dr.k20z1** · 20-02-2008 11:32 AM

roger that no1 was looking for fuel economy.. we just all got it hahahhah

Does anyone know why exactly this is the case? I assume it has something to do with colder air. Do intakes like gruppeM and mugen also result in lower fuel consumption?

driving it around 2500 is probably killing your fuel consumption, change gear around 4000-4500 will give you close to optimum fuel consumption (city drive that is)...

Really? Is that true?
