the generalization that SRI is better than CAI has already been disproven with the k-series. it was merely an example to show that CAI's DO work and are not BS. the article i posted earlier disproves the notion that underhood circulation can negate the effects of placing the filter closer to the header. it also disproves the notion that the CAI's pipe length is restrictive enough to make less power than a high flow SRI.

I never said this applies to ALL engines. BUT i offer the k-series as a PRIME example of what happens in an engine of this configuration: inatke in front, header out back.

the k-series is short stroke? the b-series? you need to get FACTS before you post. about the only recent honda 4 cyl that was short stroke was the F20C, which got replaced by the undersquare F22C.

why are we talking about turbo motors again?

 

Yes but that is one motor and one study, others have differed substantially. Theoretically you are correct though, a CAI should make more power since the air will be colder. However, this comes at the price of throttle response and in some cases that tradeoff isn't worth it.

 

yes but the reason i post it is because it affects 4B11 tuners. the engine position was a HUGE topic for the honda community back then as it is to the mitsu community now. why pave the way needlessly with R&D when that road was already paved 6 years ago?

i mean it doesn't really matter now because there are NO serious 4B11's out there with cams, P&P head, race headers, compression, etc. when or if these highly tuned NA engines start popping out, then and only then will you see the CAI become the de facto intake.

the SRI we have now is nothing more than a MAF pipe and filter. good for some hp but FAR from anything that would support the tuned engine above. cheap and easy to make, it sells because there is nothing else.

another topic is that the injen intake in my "not so expert" opinion is not optimal for the stock state of tune. you get similar gains from a SRI so why go CAI right? if you go no further, then yes. if you start tuning more and more, you will soon discover as so manu RSX owners have discovered years ago that cold air will overcome the flow restriction.

last but not least, the injen intake is a crap design imo. if the battery is in the way, relocate it or move it out of the way with a custom mount, ANYTHING. don't make some ridiculous bend to go around the thing...

basically. for this engine configuration, CAI > SRI in a higher hp state of tune. for a stock car SRI is fine.

 

one more thing... SRI gives better throttle response but there are other ways to do that as well. maybe swap out that horrendous intake manifold. a short runner, larger plenum IM would be great.

 

I'll agree with all that.

 

so you guys agrree to disagree lol


honestly, i had a CAI on my old 04 lancer, .......i probably wont get a CAI again without the water protection.....casue one day it was raining pretty hard and i went over a puddle, shortly after that my car started wigging out and turned off, luckily i was able to pull into an empty parking lot with no power steering


waiting about a minute, and turned my car back on and it seemed fine........but the power just wasn't there no more, i always thought i had messed something up ( cai/rrm piggy back/ pulley only mods), but never followed through with it

now i have an 08 lancer, just gonna get a SRI cause honestly, i dont wanna pay an extra 100-150 dollars for 1 hp extra gain, i have bills i have to pay.....180 bucks for the RRM SRI is about the most i'll pay for what little hp it gains. I've learned from the 4g94 that if you wanna go big, go turbo or buy another car.........i eventually plan to install a turbo in my car but that's down the road, and who knows, mayb ei'll save that turbo money and clean up my credit

but i'm happy with my car for right now, just do minor mods....and go on with my daily life.......i'm at a point in my life where modding my car to the max extent is the least of my worries


But to each his own.....i'll be picking up a SRI just for a little extra oomph and that bad *** throaty sound

 

i have not seen anything cheaper than that good luck

 

would putting a cone filter on the GTS be the same as the SRI? any dynos that show extra gains with a SRI vs a cone filter? 180 bucks for a small MAF pipe and cone filter is crazy imo...

 

I agree, but based on the limited availability, and the lack of compitition, $180 is what we have to pay. or $312 for Injens intake! If there was another way to secure the MAF and filter I would just use an AEM dry filter!

Oil bad for MAF!
