    No More Manual Transmission in the 2019 Mazda3 Sedan?

    I just checked my dealer's website. They have the specs up for the 2019 sedan but not yet for the 5-Door. In all trims, the transmission is listed as automatic but no manual option, although the top trim does have paddle shifters with the AT. This is terrible! I've never owned an AT in my life.

    airbox mod

    I was interested to see that members are still carrying out the airbox mod. I thought some who have done it might like an update. I originally developed and implemented the change in October, 2003 and it's still going strong, 12 years later, without any problems. I've replaced the duct tape...

    Aluminum Drums

    If the alloy drums would fit '02 Protege DX I would buy a pair. I would prefer black anodized finish to raw aluminum.

    Free custom air intake

    Yes, that's correct. Just make sure that you don't damage any internal components of the MAF sensor and you'll be fine. Good luck.

    Free custom air intake

    I believe the function of the screen is to maintain the desired laminar flow (and prevent turbulent flow) as the intake air transitions from the air box to the MAF sensor, to ensure an accurate density reading. However, a number of sources have demonstated that removal reduces negative pressure...

    Free custom air intake

    The Injen will certainly provide ambient temperature air since the filter is located in the wheelwell outside the engine compartment. However, there's no reason to believe that intake air will travel faster in an Injen than in the modified OEM intake unless the Injen uses smaller diameter...

    Free custom air intake

    There are two potential problems with SRIs. First, installing one means losing the Helmholtz resonator which is designed to enhance and maintain low speed torque. Second, there's a large difference between ambient and underhood air intake temperatures. Considering temperature alone, power...

    Free custom air intake

    Yes. To remove it, the MAF sensor must first be removed. The mesh, or screen, is a light press fit in the housing. I removed mine using a wooden dowel as a drift. Be very careful not to damage the internal components or you will surely ruin the expensive sensor. If you remove it and then decide...

    Free custom air intake

    I'm glad to see that you experienced a noticeable improvement in performance from this mod. Nice job, although you used a bit more tape than the amount I used. Also, I didn't remove my grill before cutting out the horizontal grill support. I was able to cut and remove it without detaching...

    airbox mod

    I'd like to help you out here. I have a complete write-up but on a different forum and I don't know if I'm allowed to reference it here. The last time I tried it, the whole thread was deleted and I wouldn't want to be responsible for the same thing happening again. Gains: increased throttle...

    airbox mod

    You pays your money and you takes your choice. In the case of this mod, you don't pay any money, except for some tape.

    airbox mod

    If you don't want the air intake system to ingest cooler air, don't do this mod. However, I don't see how increasing the density of the intake air in any way wastes fuel. Sure, if the MAF sensor "sees" denser air it will signal the PCM to lengthen the injector pulse to prevent leaning but, in...

    airbox mod

    Two things. 1. The snorkel passes over the radiator. By sealing the snorkel drain holes, ingestion of hot air into the air intake duct is prevented. 2. Since after modification, the air intake is located in a high pressure area, sealing all the drain holes (snorkel, Helmholtz resonator and air...

    Good job. Glad it all worked out well.

    Ignition Coil Installation Preparation

    The use of dielectric grease is not a performance option. It should be part of the regular installation proceedure. When installing a new coil pack, or replacing the spark plug wires, put a light coating of dielectric grease on the coil pack's boss. Do not put grease inside the coil boot of the...
