The CorkSport Advantage

Performance Driven

The CorkSport Mazdaspeed camshafts were tested on a fully bolted and CorkSport Turbo equipped 2013 MS3. The performance camshafts provided a respectable TQ/wHP gain across the entire RPM with a peak gain of 22.5whp. This is power you will feel across the whole RPM band, not just a top end improvement in power.

Daily Driver Friendly

Retaining factory idle quality while maximizing horsepower and torque, no worries of a rough loping idle, felt from other camshafts. This gives you an advantage in power without giving away the upgrade on those trips to Mexico.

Direct Fitment

Designed to replace the OEM Mazdaspeed camshafts for the 2007 - 2013 Mazdaspeed 3 and the 2006 - 2007 Mazdaspeed 6 models.

No Regrinds!

CorkSport Mazdaspeed camshafts are manufactured from new castings, hardened and machined to exact tolerances. No cores, exchanges, or long waits for regrinds required.

Installation & Tappet Guide

Clear and concise installation instructions included along with an interactive tappet guide excel sheet available for download.

No CEL

A great addition to any street driven mazdaspeed 3 or 6. While they don't add a lope to the sound, they do seem to give a more aggressive exhaust and they really help wake up the engine in both daily driving and spirited driving situations. The turbo spools faster and holds longer! My tuner (Erik @ DramaTune) said the added camshafts added airflow through the entire rpm range.

This is a essential mod that is normally missed.
If you have a bigger airpipe and a bigger flowing exhaust, this is a must.
Flow/port the head and this is cannot be missed.
Add the corksport intake manifold/throttle body with a good exhaust manifold and its complete.
Car sounds mean and it does not mess the idle up.

Are these cams, keyed or not keyed much like the stock are not keyed? I'm curious due to a lot of mixed ideas over keyed and non-keyed camshafts with vvt.

I know a tune is highly recommended, but will these cams work on the stock tune without throwing any CEL's if needed for a day or so every two years?

I have an ms3 bolt ons with 420HP at the wheels. With versa tuner. I want to change my OEM cams for corksport cams. IF I change the cams, do I need to tune again? Or can I just replace them and that's it? What are your recommendations? Would I have problems if I only change the OEM cams for Corskport and do not tune?

What's Up!? I'm running a 2011 MS3, fully stock with 149K on the odometer. I have these cams in my cart along with $4K worth of other mods. I someone asked about putting these in a 60K engine, would this be safe for mine at 149K?

I'm a bit confused with the results of the dyno graph, the ms3 2013 which they used to test cams it states that it was fully bolted, was the car tuned? why are those numbers low? because i have seen cars fully bolted with these cams hitting 350hp and maybe a little more(no meth). Can you clarify?
