    Good day, I'm the new guy. I tried the search engine without success. I need to replace the front/passenger side/under the coolant engine mount (commonly refer to as #3 ); can anyone provide the OEM P/N or other? Many thanks

    Hi all, wondering if anyone could help or advise. I have a Mazda 3 2014 2.5L Skyactive SportNav, I had the clutch changed last year and a short while after i noticed getting into gear (1,2&5) seems rather stiff sometimes. Its more noticable when the car is under acceleration, down shifting is...

    2.5L - How much oil? Engine feels a tiny bit slower?! Well thanks to a suggestion on reddit I finally am able to use my dipstick. I have never had a problem on any other vehicle but on this car the dipstick flat out didnt give me usable measurements (not accurate or precise), my father also...

    Now that I do not have my 2011 MZ3 any more time to sell off a couple parts! I'm selling my AFE Takeda Cold Air Intake for the 2010-2013 2.5L MZ3s. This CAI actually routes down to the bumper, getting that nice cold air, coupled with a tune it sounds and performs great! I drove on this setup...

    Hey guys, so my check engine light came on randomly while I was driving on the highway, there was nothing I can say was happening when it went off. I was not speeding, didn't go over any major pothole, nothing? Any ideas what it could be? I recently had a lot of suspension and break work done...

    Putting my stock airbox back on and eventually selling my axle back muffler. Its still in great shape, the air filter needs to be cleaned. I have upgraded screws for the air box. The entire intake is black. The Intake is for the 2014+ 2.5L only, it will not fit the 2.0L. The box fits...

    So I know this is isn't important but it's fun to look at the numbers. OV Tuned + Corksport Trans/ Rear motor mounts. I could even do slightly better with better shifting but whatever, I have more fun driving the back roads. Still slow! Lol.

    Hello Everyone, Looks like Cork Sport recently came out with a "plug and play" electronic 72mm throttle body upgrade for several Mazda platforms, see link below. I didn't see our Mazda 3 platform listed in the compatible models list. I've reached out to their Sales contact to see if an upgrade...

    Cork Sport 2.5L Header Product Request Hello Everyone, I've been bugging Cork Sport about developing an exhaust header product for the 2.5L engine for a while now. I was pleased to learn that Cork Sport has experimented with headers for the 2.5L and have observed appreciable performance gains...

    Hey all, I have a Corksport 2.5L SRI and the Corksport cold air box that goes with it for sale. The combo has a whopping 400 miles on it since my wife really wasn't into the additional feedback from the engine as much as I was. Sounded great to me! :) Due to this, you win! Colors: blue...

    Ok, Here's the story. I got the old belt off with no sweat. When I tried to match the new belt with the old belt they appear to be the same size/length. When I tried to install the new one I cannot get enough slack in the tensioner pulley to get it on(couldn't slip on to the crank pulley). So, I...

    Hey guys, Just asking around if people have experience with JBR coilovers. Its that time of the year where I randomly have the urge to research parts for cars but I never really pulled the trigger to buy some high performance parts for my car. I am really a noobie, but I do wonder if coilovers...

    Ladies and Gents, I have found a few threads regarding the RMM on the 2010 Mazda 3 2.5L M/T, it seems to be different than the older ones and hard to come by. My local dealer wants $315CAD for a new one. Is there really that big of a difference between the 2.3L and the 2.5L? I can buy an Eagle...
