we should make this a sticky for our daily drivers!!!



stock air boxes are so restrictive. i added a CAI and TB spacer to my Jeep and it improved lb ft, hp, throttle response. it was well worth 75 bucks. which was a huge steal considering the TB spacer is about 60 bucks by itself.

Airboxes are restrictive for a reason. Granted you'll get 1 or 2 hp up top with it gone, but you'll probably lose at least that elsewhere in the range. Mazda put good money into designing the intake, don't be so quick to assume you can do better with a $75 filter.

Makes sense, but in all honesty, how much does it matter?

Not a whole lot really, I'm actually a hypocrite because I have a sock filter on mine - but it's all that will fit under the bonnet.

reasons are gonna vary from car to car..

you cant make such a general statement unless you know the factory tuning for this specific car..

and what the reasons are for the restriction..

k&n ran me a whoppin 35 buckaroos that will pay for itself in the recycling aspect alone...

removed the tray and resonator located inside the box that impeded airflow..

It's a little like exhaust tuning, most if not all manufacturers will aim for an even powerband rather than all out top-end power i.e. an engine that is more driveable. That's the cause of the restriction, although that doesn't necessarily mean restricting your intake will give you more torque.

Yeah, I often read about that in motor trend. I was surprised that I could easily hear the stock intake of my buddy's Mazda 3 hatch.
