question on 200tq tuning

[Ben Swann]

Paul,

I concur with Bernie on the K&N - you won't believe the stuff that can slip through these things.  More importantly than in the older CIS cars, the oil that is required for proper filtration on the K&Ns is detriment of the MAF sensor.

Regarding the tires, I have 225/60's on mine. They are a bit oversized, as in too tall.  The 225 width is fine, so probably a 225/55 is more appropropriate.  Check one of the tire size calculators online such as http://www.miata.net/garage/tirecalc.html to find your best fit, but the 225/55 will probably handle better, not rub when fully loaded and cause less speedometer deviation.

[Yeh, dump the K&N quick!
