GENUINE MAZDA OEM Intake Solenoid for Mazda RX8 (Series 1 & 2, 2003-2012) GENUINE MAZDA OEM Intake Solenoid for Mazda RX8 (Series 1 & 2, 2003-2012)

Happy 8's day people! For you series 2 owners, here's the easiest way I found to change these little suckers. RX8 Upgrades providing the genuine goods as always. Remove the air box/ CAI, remove throttle body and remove the top part of the UIM only, this will get you easy access to the solenoids. Now you could remove them from this point, but removing the oil filler neck along with the vacuum chamber the solenoids mount to makes it FAR easier to change them. This whole job can be done in an afternoon for a mechanically minded person. On reassemble, don't forget to place the vacuum reference back onto the bottom of the manifold (has a green check valve) otherwise no valve will work. Reassemble and enjoy. PN is KL01-18-741 for those chasing the part

AUTOEXE Lower Arm Bar (Rear) for Mazda RX8 (Series 1 & 2, 2003-2012) AUTOEXE Lower Arm Bar (Rear) for Mazda RX8 (Series 1 & 2, 2003-2012)

The rear lower arm bar is very nice and strong. There are 4 pieces two triangular bars for the subframe and two smaller bars that strengthen the rear arm. Overall I'm very happy with the bars. The quality of the autoexe bars are excellant and the packaging and handling of the bars are superb. I found my turn in using the autoexe bar was more responsive then my old Cusco lower arm. As well my rear is more stable when exiting out of corners. The best part about these bars is probably the front member brace and the triangualar rear brace that strengthen up the chassis. Because with my current suspension setup to the max and without my roll cage installed yet, my cars chassis is flexing from the pressure and stress buildup that I put on it at the track. For the price I'm very satisfied. Even though the price isn't cheap and in some cases you can buy a car, but the bars are definatley worth the money.

GENUINE MAZDA OEM Spark Plugs for Mazda RX8 (Series 1 & 2, 2003-2012) GENUINE MAZDA OEM Spark Plugs for Mazda RX8 (Series 1 & 2, 2003-2012)

I went ahead and replaced them on our 2014 Grand Touring AWD after almost 5 years and 60k miles. I know the manual says 75k miles but I figure it was time given the high compression ratio SkyActiv engines and the lots of stop and go seen by this car (my spouse's hour long city commute). I got the Mazda OEM plugs (PE5R-18-110) despite their high cost, given the experience of others on this forum. Very straightforward job: remove the cover, remove the bolts holding the ignition coils, unplug connector for each coil, and remove and replace plugs. After seeing them I'm glad I replaced them.

Performance Upgrades and Genuine OEM Replacements

RX8 performance upgrades should suit the purpose of the car rather than chase a one-size-fits-all result. The right components can improve response, control, cooling, consistency, sound or driving feel, depending on the system being updated. Consider how each part works with the rest of your setup and choose upgrades that make sense for your ownership goals.

For components where factory fit, calibration and known-condition reliability matter, a new genuine OEM part is a practical alternative to a used item with an unknown history. Genuine parts help retain the intended fit and function, making them a sensible choice for restoration-minded owners and for reliable replacement work.

Series 1 and Series 2 RX8 Fitment

Check fitment carefully before ordering, particularly when comparing Series 1 and Series 2 cars. Parts can be specific to a particular version, system or configuration, so confirm the product information against your vehicle before making a final choice. If you are unsure which option applies to your car, seek fitment advice before ordering rather than assuming parts interchange.
