well, you guys can say that, but i had a CAI on my yaris before, rained few days straight, it was parked outside so maybe water dripped to the pipping and found its way to the filter, and got the filter wet, i was driving to work, in the morning, and i gunned it to merge on the highway, and the engine stuttered, i tried gunning it agian and same thing, so the whole way to work i took it slow, so as a daily i am going with short ram

 

Injen is making bold hp/tq gain claims.

I have sat in the AJR Fit and the throttle response is really good with the intake.

I used to have a F5 SRI in my GD3 and replaced with the T1R intake. Powerwise, my butt dyno didn't feel too much of a difference but The T1R intake does have much better acceleration and response in mid-low speed. That made the car funner to drive.

 

I just got a 2010 sport, and was looking at the stock airbox and was wondering if anyone has tried opening it up a bit?

My old car was a 08 MazdaSpeed 3 and although i put a Cobb intake on it, it was a well known mod to essentially cut the part below the air filter off. Intakes for the Mazda were also half the cost of what they seem to be for the fit though, and got 3 or 4 times the hp gain.

Anyways, let me know if you have given it a shot!

 

Can anyone let us know about the difference in sound. I was leaning towards the prm but the t1r looks like it might be a little quieter which for me would be a good thing. I'd love to hear your opinions.

 

t1r is almost like stock sounding. prm screams but also works better. if your gonna spend this kind of money on a intake i say injen cold air. i have run both prm and t1r.

 

Can he even use an Injen? he has an automatic, i didn't think any of the Cold Air intakes would work.

 

the injen will work with auto's

the prm is very good intake, its a little loud, but i think its not as loud as people say it is
and its only loud when you gun it otherwise its stock sounding, also with the prm you hear the vtec every time @5500

 

or save you money and do the custom intake. costs from 20 to 65 bucks and works just as good. search ge8 custom air box.

 

the injen cold air might be like my particular PRM, the long (cold air) that fit the manual only, filter sits by lower radiator. That keeps the noise down somewhat in the cockpit, but still sounds great. I like it a bunch.
However cant add really anything on the others as I have not tried them

 

Without an exhaust you wont have a lot to worry about anyway. The PRM piece is top notch.

Any intake will make the engine growl when you lay on the throttle, but w/o an exhaust its just a growl, not obnoxious to those around you.


I bought the PRM and eventually an HKS exhaust to try and help the L15 breath, as I drive about 170 miles a day during the week. The PRM intake added 3-4 mpg from what I can tell, and the exhaust helped maybe 1 or 2 more.

Right now my dash is reading 42.6 mpg on about an 8000 mile trip, as we all know it is a bit generous. However, earlier in the trip mileage I was down around 38, so to pull the average up that much means I'm proibably hitting 40mpg.

I'm not going to waste time putting the figures together.. I've had the PRM intake since about 6 or 7k miles on the car and am at almost 47k now. If it hasn't paid for itself in fuel savings, it will have soon.

 

That's a very goOd write up om the prm. Thank you.

 

I know GarageFK likes the PRM intake. I went up their yesterday, this is the shop that has outfitted a GE with a K20 (don't even ask how much...OHHHH PHUUUUUUCKKKKK!!!!!). Anyways they liked the response of the motor, of course most of that ties into the throttle controller, but he said it's the quickest GE (barring the K swapped one) that he has worked with.

 

check out the problems this 1 member is having with his T1r intake:

I will be going with the PRM universal on my KWSC intake tube....

 

Not true...at the very least, unverified. I challenge you to produce a dyno graph showing gains with the "hack" air box on a Fit. People (formerly myself included) think an intake is an intake is an intake. Why do you think these companies even R&D their products? Why not just invest all that money on shiny tubing and bright colored filters? The reason is because the air velocity, turbulence, and location of the sensor along the tubing all matter...air temperature is not the only variable.

It amazes me how people just throw crap on their car and don't verify the results. Probably 25% of the people riding around with CAI have negatively impacted their performance. The other 50% likely have had no measurable effect on hp/tq. The modern engine is so complex (and the average tuner so naive) that simply changing the intake can cause dramatic changes to the air-fuel ratio (i.e. cause the engine to run "rich" or "lean"). Using the same intake on identical cars can produce different results (even testing at different times on the same car!!)...because of all the variables involved.

One of the tuner mags this month reviews four different air filters on a 350z test car. I don't remember which mag, but you can flip through the big ones...and an hour at the bookstore will be time well spent. I recommend you educate yourself rather than taking to heart what is posted here.

 

exactly! QFT

 

Looking back...I think that post came off a little harsh. LOL

 

Yeah you tend to do that at times.... You were right about what you said though. There are a lot of people that have had to resort to installing catch cans on N/A engines due to blow by created by loss of ring tension caused by high combustion temperatures.... The ECU can only do so much with 87 octane fuel and a lean A/F ratio and it isn't enough.
