Hi there,
I'm looking for a CAI, spark plugs, air filter , some lights and a fin antenna for my mazda 3, sedan, 2.0L, 4 door. 2008.
Looking at www.therpmstore.com the following parts sound appealing
VG Shark Fin Antenna for Mazda 3 / Mazdaspeed 3
GT SPEC Radiator Cooling Panel for Mazda 3 Sedan
Smoked Rear Reflectors with LEDs for Mazda 3 / Mazdaspeed 3
Denso Iridium Spark Plugs (heat range: one step colder or stock)
AEM Cold Air Intake for Mazda 3 $249.95
F5 Fujita Cold Air Intake for Mazda 3 $209.95
Injen Cold Air Intake for Mazda 3 $239.95
K&N Replacement Panel Air Filter for Mazda 3 $49.95
K&N Typhoon Air Intake System for Mazda 3 / Mazda 5 $239.95

about the spark plugs: what does it mean "one step colder" or "stock"
as for the CAI: Injen and AEM seems to be the choice in this forum, what do you think?

Additional note: wheater conditions here are between 82 to 93 degrees Fahrenheit (yeah, it's hot down here).
Also, we have heavy rains so im looking for a CAI that, due to positioning, wont expose too much to hydrolock.
Looks like the Injen is better than the K&N in this matter....comments?

thanks,
