Hey guys,
I just replaced a 2011 mazdaspeed3 with a 2009 fit to cut down on costs. I like the car, just desperately need more power. I'm not sure I want to go the FI route. Any relatively good bolt-ons you guys recommend that make a decent difference? Obviously not looking to be as fast as my last car... Thanks for the input.

 

The simple answer is no. Based on what the more gear headed members have said, the ecu nullifies the simple bolt-on improvements like CAI.

 

Well that sucks. I guess I need to save my pennies for a while and go FI. Thanks for the honest reply.

 

15x7" Enkei RPF1 ultra light racing wheels and 195-50-15 tires is about the best performance mod other than boost...Even with 10psi, ECU reflash and trick exhaust you can feel an increase in acceleration with the light wheel/tire setup once the tires hook up..

 

Even boost is going to have to be a custom job as there isn't a widely availble turbo kit...sorry At least it's a good looking car.

 

Should have just kept the MS3

Oh well, welcome, and enjoy.

 

Welcome, best starter is light wheels and tires. Will help all around.
