Good-Win Racing Monsterflow Intake


Pros: Excellent throttle response. Gives your Miata a nice growl sound.

Cons: I sometimes feel the sound is a little tiring.

When it came time for an intake for my Miata, I decided to go with the Monsterflow intake with the polished aluminum crossover tube and cold air box which I bought from Good-win Racing.

This is definitely not a big power gainer, but the added throttle response is very welcome. When combined with a header and exhaust, the power gains are very nice though.

I have had a lot of people ask me if I think that the cold air box is worth the money. A friend of mine has a pyrometer (measures heat) so I decided to test the heat difference. We found that temps inside the box where at least 30 degrees cooler than the temps on the outside of the box. So in a nutshell, yes I think the cold air box is worth the money.

Unfortunately, at this time, I do not have install pics for the intake. I installed this while I was at Thunderhill doing a track day; while it was a perfect place to test the intake, it wasn’t so great for taking my time and documenting the install. Maybe one of these days, if I am bored, I will reinstall it and take pics to put up here. The install is quite easy and can be done in less than an hour and is completely reversible.

    Greetings sir,
    I recently purchased an ’03 Miata with a K&N Typhoon intake. I have been search for the last few weeks for a cold air intake that will fit it. The Monsterflow 17-1006C appears to be shaped appropriately.
    Unfortunately, this unit is no longer available from Good-win Racing. Do you know of any other suppliers??
    thanks, bob

    I just bought a used Miata with this intake. Do you have a copy of the orignal installation manual that maybe describes how the filter should be maintained? Thanks!
