SUP PEEPS!

as long as mike is here... i'm good :fistpumping:

I dunno how restrictive the stock intake is on a Mazda 3 but anyways, most "Cold Air" intakes aren't true cold air intakes.
I think a cone or drop in filter is just fine for non-turbo 4 cylinders.

EXPLAIN PLZ

Most cold air intakes from these companies leave the cone filter where the stock air box would be, leaving it to suck in the warm air inside the engine bay.
That's not a cold air intake, get a cone filter for your car, it'll end up doing the same thing as a $100 piece of pipe.
I'd rather get a drop in filter though, most factory airboxes these days have a pipe that leads to the outside of the engine bay so it actually sucks in cold air.
If you get a drop in filter, more flow than a stock filter, and actual cold air! Win!

Molding plastic for what use? Could be a different grade of ABS. Of probably about 15 different auto parts manufacturing facilities I toured for work, only one used primer on their ABS parts (mostly because their process sucked). All the rest of the places tried to avoid primer like the plague. The coatings cost far more than the plastic, so if they could get away with not using it, they would.

Most of the parts were used on riding lawn mowers, others were used for panels for air purifiers.

I'll have to check where my stock filter is, but I know the Corksport SRI and single exhaust frees up a good number of ponies with a dyno sheet to show. I'm looking for the thread now...

Also, this -> is hilarious.

Although the short ram intake might free up some horsepower, once the engine bay is hot and the intake become heatsoaked, you'll lose horsepower.

[AZ89two4Tsx]

You should just run the filter inside your car so when it's hot you can turn on the A/C!

Then BAM! Instant cold-air intake!!!!

[ADDirishboy]

Gee, that looks familiar. DO EET

On second thought, keep looking. price is too high. http://www.kbb.com/kbb/UsedCars/Pricing ... h=Trade-In[/quote]

Yea, I'm gonna keep looking around. Wait for a good deal to roll around then jump. As long as the Mirage is still running, I'm in no hurry.

[krimsonviper]

I'm not interested in short ram, just the CAI because it's being offered to me at what sounds like a good price. I only pointed it out because you asked how restrictive my system is.

[Razi]

You needz boost yo!

[krimsonviper]

You needz boost yo!

Word to your cultures delicious foods. Not happening on this car. I also want the intake for a little bit of free power and to help increase MPG.

Also:

Utilizing the single exit exhaust and the Short Ram Intake, we went from a baseline of 118hp/110lbft of torque to a respectable 135hp and 123lbft of torque at the wheels. We're still working with the intake on this one to get the most out of it while retaining factory fuel trims. The 2.0L results were moderate (with around a 4-5hp/tq gain) below 4000rpm with the majority of the gains came on rapidly at around 4500rpm and held steadily to the 7000rpm redline. This really shows how constrained the stock system was for the smaller 2.0L engine.

What company it's coming from has a lot to do with it's price: Injen.

There is a lengthy article on CAI's here somewhere. I'll see if I can find it...

probably your best bet

[krimsonviper]

The dyno results on this combination of intake and exhaust were equally as impressive, but dynamically speaking were a bit different from the 2.0L. Where the 2.0L opened up quite a bit at the top end, the stump pulling 2.5L exhibited up to 20lbft of torque gains in the midrange with a consistent 10-12hp gain through the entire powerband. Stock Peak HP & Torque were 158/161, and the intake and exhaust built 171hp and 171lbft of torque.

Good grief, that 2.5 motor has some potential for N/A. I heard it has some forged internals as well.

Sweet! Let me know, I need to read up on this if I decide to make a purchase on an intake at any point in life or give info out. :fistpumping:

[AZ89two4Tsx]

Those are decent numbers for an intake an exhaust. Make sure to look at the conditions though. This was at 72 degrees, pretty optimal conditions.

I myself would go to a muffler shop for the exhaust as it would be basically the same thing. Especially in CA where you don't have to worry about rust.

As far as the intake, it depends. How restrictive is the Mazda 3 factory one? As Razi said, most newer cars have pretty decent intake designs.

If I really wanted to tune my car, I would take full advantage of not having to smog new vehicles their first 5 years and cut out all of my exhaust restrictions.

I searched, and I can't find the damn thing. I wrote a fairly lengthy one a while back, and I think Matt did also.

Wait, is that what you think you're at, or what you're building to?
At: Good grief that's good power for an old engine, but you're pushing 2 more cylinders than the 4-banger. Still, that's some good damn number!

To: Hope you can get it!
