OK, the intake "resonator" is on the bottom of the "T.B. Boot" correct? (The T.B. boot being the big 3" black tube that goes from the back of the MAF to the T.B.).

On the bottom of that tube is the intake resonator.....

Is it ok to remove it? I removed it on my 90 maxima with bo probs, but I'm wondering if it's ok to do it to these cars (cover up the hole obviously) and everything will be ok? (I.E. no sensors are attached to it, etc?)

Let me know... Thanks in advance.

Yes, it will be alright to remove the secondary resonator provided you plug the hole.

The positives/negatives:
Mazda engineers designed that secondary resonator with function in mind. It helps produce torque. By removing it, you will lose maybe 2-4 lb-ft of torque, but pick up 2-4 hp.

Dont believe me? It has been dyno proven! Search PT for the proof!

would it improve my Miles per gallon? That's all I'm really looking for. I don't care about moving "quickly".... just improving my already great gas milage (29-34mpg avg)...

So since more hp is avail, it should mean better MPG, right? But it's torque that moves you.

I doubt that the mpg will change anything relevant.

The F2 usually gets about 28-32 mpg (highway).

My PGL averages 270 miles per tank before I refill (15.1 gal tank - refill about 12 gal).

The best tank I recall was ~440 miles and only ~11.6 gal to refill. But that was all highway driving from Southern California to Colorado.

It shouldn't make any difference in fuel economy, but it will make more than a 2-4 ftlbs of torque difference.

At least it did on my car. I decided to test the difference out, and my butt dynometer could tell the difference. Admittedly I didn't to a double blind test, but it was noticable.

Don't bother taking it out permenantly, it isn't worth it. But it can be helpful to take out temporarily, if you are doing test drives on the car to trouble shoot other problems. Lord knows it seems like you have to take out the throttle body boot if you want to do any work on that side of the engine. At least those of us with big hands have to take it out. Ugh.

Cool... thanks for the info...... It's staying in.

yes, the resonator does increase mid-range TQ. i was the one who dynoed it this year back in april. but when you take it out, it makes the engine sound sooo nice.

... as in "nicer" under WOT, correct? (you hear the intake filter more)..... well, as was the case on my old maxima..
