MAZDA 3 Home made Cold Air Intake

I made this CAI for my 2008 Mazda3 1.6L. Ived constructed this CAI using radiator hose(2.5" inside diam., commonly used on trucks), 2.5" aluminum pipe (which would house my MAF and vacuum hose) and 3" Simota Air Filter. I used hose clamps to hold them together and to connect it to the throttle. Also, I used an Epoxy Clay Steel to mold the flange on the aluminum pipe for the MAF and 2 bolts to hold down the MAF in place. The Epoxy clay hardens like rock and sticks to the aluminum well, it also can withstand high temp. I routed the rubber hose down at the back of the front bumper, where I placed my Air filter. This way it can suck colder air which is the main goal of CAIs.

Cold air intake Principle
Aftermarket air intake systems are among the most common and least expensive methods to increase horsepower. It is a simple bolt-on kit that consists of a conical air filter fixed onto an inlet pipe. When it is installed, the inlet pipe starts from the top of the engine and makes its way down to the outside of the engine bay, and the conical air filter is fixed onto the lower end of the pipe. The conical filter can now breathe the air beneath the engine, which is cooler than the air being brought in by the stock air box. This is why the setup is called the cold air intake system. Cool air is denser in oxygen molecules than warmer air, resulting in a more powerful combustion when mixed with fuel.

Horsepower gain varies depending on the brand of the intake and the engine it is bolted to. Typical gains are in the range of 5 to 20 horsepower. Cold air intake systems generally cost around $100 to $400 and there are a number of reputable manufacturers, including AEM and Injen, who carry a variety of models.

[arnoni11]

should of made it all metal it wont last long

[samtongken2008]

@arnoni11 replaced it already and constructed one made of stainless pipe...works great...will post video soon

Question did that part with the MAF sensor come on your stock intake and did you cut it off of the stock intake and put it on your custom intake?

Nice cost effective intake. You need to post a vid of you driving it now...

[samtongken2008]

nope.i made a mold of the maf flange for d custom intake. its wise to keep ur stock intake in case you want to go back to stock, i do that whenever i bring my car for maintenance at the dealer. theres an issue in warranty if they found out ur using a diff intake or aftermarket intake and other engine mods.

Remove the poor porn music and then I'll be able to understand you better

[r2rrita]

basically, basically thats all i understood..

cold air intake is for higher RPM ranges (4k above).. If you have a 1.6L most likely your in a place or country that averages 50km/hr-100km/hr the most..

Having a SRI will suit your road condition better.. SRI are better in low end torque.. 3.5k below

[oiram1189]

I'm starting to get worried! I've been reading and people say this thing blows up the MAF sensor or that eventually I'll get error codes or something? Is it a myth? someone?

[oiram1189]

Ok, FINALLY I bought one for mine! The sound it makes is awesome combined with my borla exhaust! But...what about the power? I've seen improvement in first gear at low revs, in mid range revs at all gears and almost none at high revs (x4300 +) have to clarify that mine has a 1.6L engine with a 4 gear AT transmission (LAME gear box) If you have the same combination then you'll understand how underpower the car feels. Nice video btw

[sojanxrae]

yo good shit but you knw even tho u may hav got a small gain think of it this way read up see witch company has a better shape pip c.a.i. and ull really notice an increase bu yo if u tryin to just get the sound for cheap thats a grate home made one least it looks ligit thumbs up on exploring

[Tdapbxtch17]

Where did u get the air flow thing from

[dabaddon]

@samtongken2008 so....whatever happen to that video with ss pipe

[dh39zj]

@Superguerrerosongoku ........great vid bro.

[oiram1189]

@Ryantube007 Do you think that by reprograming the computer again once the CAI or SRI is installed it will gain the lost power back? or it is what it is and there is no way on earth I will gain the power back?

[oiram1189]

@Ryantube007 Thank you man, I had an issue with my new exhaust, my mazda had the 1.75" and I upgraded it to the 2.25" exhaust and experienced a loss in power, A LOT of power less.Took the car to the dealer and they reprogramed the "PCM" (That's how they call it here in El Salvador)I guess that's the car computer and gained all the power back.

humm, i saw my cold air temp.. they are usually high cuz of radiator. any difference in ur's after that mod?
