i recently did research on the CRX and they get 40/city and 52/hwy brand new Im just curious what ppl get in them. I have gotten the most 47mpgs and the least ive gotten with cold air intake and bad plugs is 32mpgs. I recently put back on stock air intake to get my mpgs back up.

 

does it really help to have the stock intake on?

 

It helps a whole lot to lessen fuel consumption. it sucks on performance as get up and go wise. I drive mostly hwy mileage to see family and it saves me money for less fuel consumption.

 

damn im messing like 3 parts to put my stock one back in. ive been have low mpgs

 

oh thats not good. Well I know from experience no junkyard that i have searched even have crx in the yard for parts.

 

Well I found moat of the parts. But does it really make that big of a deal? I thought with a cold it it actualy helps more than the stock intake

 

well it does make a difference in gas mileage. I put a cold air intake on my CRX and my gas mileage went down after that but boy it could get up and go with the cold air intake. I finally just put stock back on for the gas mileage.

 

I have seen HOT air intakes to increase MPG with proven, mesurable, increased MPG.
This guy knows alot and gets 70 MPG. ===> http://www.crxmpg.com/

 

yeah i read that article and if you notice he did a whole engine swap for fuel mileage. that takes time , money and experience. I have time and automotive experience just not the money roflmao

 

has any body besides JuneBugDrfter notices any loss in mpgs when using a cold air intake?

 

My 89 hf got 45 till I put the b16 in it

 

118 MPG lol

I thought that a cold air intake was better for mpg on the terms that a cooler engine runs more eficiently

 

Correct me if im wrong, but i believe that once you introduce more air into the engine, the fuel has to compensate for the air. so, your air:fuel is shot to **** once i induce more air.

I think bottom line is that, a stock intake inducts less air, then lowering the air:fuel.

 

thank you this is so true more air equals more fuel.

 

I have an AEM short ram, **** i need to find a stock box/tube for my eg so i can cut down on going to the damn gas station!

The only "work around" to this is to have an adjustable FPR. But then you'll be running lean and end up with different problems all together. Honestly, i think that you only "need" a short ram or cold air if you plan on doing something which requires quick acceleration. Its a waste of gas on a normal daily driver.

 

i got 53mpg on the hwy with stock intake and exhaust manifold. that was the best ive ever had. i was driving at 70 most of the way. took me <1.5 gals to go 75 miles. i havent tried to see what i got after intake/header/exhaust yet

 

when my crx hf was stock i got 50 easy, 55 if i was gentle. When i put in the si transmission i could only get around 43mpg.

what kind of mileage should i expect with a sohc zc (non-vtec) + si transmission?

 

The highest I got when I had my HF was 56 on the highway.

 

I think it was a bad idea to remove my restrictor plate and put the intake on...

 

wow good fuel mileage and hey what bout bosch platinum 2s would that drop gas mileage?

 

i just read some where here on HT that bosch dont do good with hondas and that NGKs are better to use

 

oh okay ill look into changing my plugs to NGKs for better fuel efficiency

 

im actually doing this, got the engine/wirings/and ecu already. 300 bucks !! LOL

 

okay so i changed my plugs but now my fuel filter needs to be changed i got 32 mpgs on last fill up and my crx got sluggish on uphills so am i correct fuel filter?
