How To Install The Crankshaft Pulley For Mazdas
It will take you 45 minutes to install your CorkSport Mazda crankshaft pulley with our easy-to-follow instructions.
Excellent piece. The original crankshaft pulley was rusting so I thought time to upgrade. The Corksport pulley is light like a book. The factory pulley is like “ a lead pizza” Now our Mazda 3 purrs and you can feather the accelerator- nice and smooth . Also looks like I got 5-10% increase in fuel efficiency. I did not get the rear engine mount. I wanted smoother acceleration and I got it. Thanks!

i wont comment on the weight savings because this is quite obvious.
i wont comment on the craftsmanship because this is quite obvious (corksport).
initial impressions once installed are "meh." im thinking this pulley is more noticeable in manual transmission cars for rev matching. the only *noticeable change you'll feel in automatic is off-pedal deceleration; the car slows itself down quicker.. it is strange to me because, by this logic, it should accelerate quicker? i honestly feel no difference in acceleration. either way, this is a fairly inexpensive mod and a beautiful piece. i haven't driven enough yet to see if there's any mpg gains, but i figure there would be a marginal increase (maybe .5-1mpg city via easier rotational stop/go).

Just installed this on my 2015 Mazda 3 and I wish i had installed this earlier.
I have the Corksport rear motor mount and it would make my car vibrate like crazy when the A/C would turn on. I installed this and it runs much smoother now with the A/C. The car also shifts smoother.

Im very very happy to purchase all this products (crankshaft pulley, springs, intake system, cat back. ), it's taken my car to a really another level... I'm very pump to see what left to come. :-) [Mazda GTS]....

This part was surprisingly more affective than I had anticipated. It made a noticable difference in the neutral throttle response (notice NEUTRAL, not nearly enough difference to notice while in gear). The engine revs up faster and makes matching gears much easier, and between shifts the rpms drop fast enought that the smoothest way to shift is fast. Fairly easy install aside from getting the pulley bolt off (125 psi impact gun wouldn't do it, I had to heat up the bolt a bit to break it free). Other that the bolt everything was very straight forward. Surprising bang for buck, great part.

Will this fit a 2012 mazda 3 Skyactiv or will you guys be making one?
CorkSport Reply:Check out our FAQ for an answer to this question.
After install this will involve our engine mounting or NVH? Currently our Mazda3 Skyactiv have slightly vibrate when engine idle (mine idle at 700rpm) or make a full brake (20 to 0km/h) when acceleration, I'm sensitive with those vibrations if this can solve my problem (minimum vibration) that was a great choice for us.
