Mazda b2300 cold air intake?

I was going to put a K%26amp;N Appollo cold air intake onto my 1994 mazda b2300 as a way to improve gas mileage and horsepower but what would the gain be in horsepower and if I put it on the truck are their any harmfull side effects.|||well,

it does improve the mileage on the car, and certainly the horse power (10 to 15% more horse power if you dont use any reducer hoses).



the car will be roaring (you will hear the engine noise more depending on your engine and the intake hos length -small hose= more noise= more power=more mileage, long hose, well you figure it out).



the may-be harmful side effect is that the air-fuel percentage will not be the same anymore and it can doe the opposite effect on you car , ie you will lose horse power, and the car will consume more gaz, BUT that only happens with small engines like a vw polo 6n or so.

if when you install it and when taking off , your car kinda chokes, it means its receiving a lot of air.

here a solution i came up with:

in order to reduce the air volume i took the kn filter off, and taped its outer side (where it sucks air), it reduced the air volume the engine sucks in and it worked just fine.

good luck|||You didn't mention whether you're driving an automatic or manual truck. If its an automatic, the performance increase will likely be hardly noticeable, since the CAI will only improve the upper-end numbers, and only by a small percentage. It will improve your gas mileage by 2-3 mpg as compared to the stock unit.





The down sides: First, if you operate your truck in a dusty environment, you will be letting some more particulates through the K%26amp;N filter - these particulates can act like sandpaper on your cylinder walls. I'd suggest putting a filter sock on your filter if you do drive dirt roads and such, and pay attention to the service intervals on the filter - cleaning and re-oiling as necessary. And second, and this depends on whether you consider it a negative or not - you might get a little more intake noise back through the filter. On some engines, it can be a little obnoxious (although on my LT1 - its not noticeable at all, since I have a 3" exhaust on it!).





As far as the fuel/air trims being off on your truck (as the other post mentioned), that will be very doubtful unless you are installing a short "ram-air" type CAI; on regular style CAI's the fuel trim will be relatively unaffected, since the MAF will see the added airflow, the O2 sensor will still receive the proper range readings, and the ECM will compensate - particularly on a stock head, stock intake truck.|||Don't bother.



The cylinder head flows so poorly that slapping on a stupid air tube isn't going to help that.



I had a 94 Ranger with that same dual plug head four cylinder in a past life...air intakes are not the problem there.
