i want to get the mazda6i and i want to add a bit more power in the range of 175hp or more.
what kinda of performance mods can i do to achieve these numbers?
like i kno intake headers and exhaust, but i want to kno which exact brands and models are available and which upgrades are best bang for your buck.

 

For your 6i id say go with the mazdaspeed CAI or cp-e intake. The mazdaspeed intake you get the warranty and it is a great intake. The cp-e is the best you can buy but it is 500 bucks. I wouldnt suggest getting it unless you really want those couple extra horses. With exhaust they all are just up to your liking. You can go to websites and they have sound clips of the exhaust so you can hear the sounds. I dont know if anybody makes headers for mazda 6. Good luck

 

it's gonna take a bit to get above the 160whp mark (dynojet) but your typical intake/exhaust & header when it comes out. should set you up close the 160 mark at least.

 

i have the same question regarding the 3.0L, any suggestions on brands for
intake
ecu
exhaust
strut tower / sway bars
ingition
and is there a way to tie in a external sub to the Bose system, w/o interfering with the o.e. stuff?

 

i don't think that just an intake and exhaust will put you over that mark for wheel hp. maybe crank, but not wheel

 

well, i started with 128 with my atx and got up to 140 with an intake and prototype header. given a production header would put me in the 148 range or so (given what it did on the focus)...then figure in the mtx dynos about 10hp more than the atx....and you are within 5hp of your mark. not too shabby.

 

i realize the types of gains from the add ons. The question was what are good brands to get. obviously you could get some crap like pacesetter and save $, but there are better and best options. the only site i found that seemed to have pretty expensive stuff was cp-e. anybody else have input on brands like injen or AEM?

 

well, there aren't many options out there really. almost all the intakes put out withint 4hp of eath other on the 4cyl....but only 1 can assure you that you won't have a CEL. headers....GTSpec is the only option right now....so again, you don't have a choice. exhaust....doesn't do all that much until you start opening it up, so just pick whatever you want.

 

Mr tea are there headers out there for 06 mazda 6s? ive searched and can not find them.

 

don't know what the differences are in the year on the V6? sorry

F2 is working on something, just need to test fit it on a newer setup....that will work for sure, just take a couple months.
