AUTOEXE Premium Cat-Back Exhaust Muffler for Mazda RX8 (Series 1 & 2, 2003-2012) AUTOEXE Premium Cat-Back Exhaust Muffler for Mazda RX8 (Series 1 & 2, 2003-2012)

Just installed my spanking new Autoexe Stainless Muffler, and here's a short take of my initial impressions: The Autoexe catback is lovely - very unique 2 box design and the tips are the tapered kind (ie cut at an angle) each lasercut with the Autoexe logo. Very nicely polished midpipe which connects beautifully (and easily) with the exhaust outlet. Most importantly, the exhaust tips have a perfect visual alignment, unlike other exhausts i've seen where one tip protrudes out more than the other. The Autoexe definitely doesn't have this problem. Also, the 2 box design has a lower profile than stock. Previously, i used to scrape and even dent the exhaust box when clearing humps or even parking - not so with the Autoexe. The Autoexe performs really well, at least on my AT. There is a noticable increase in low end torque, and the car just feels substantially lighter. Revs are much more responsive, and the slight lag felt when launching the car seems to have melted away. Linear acceleration is also much faster (at least across 1st 3 gears), and i'm reaching 120-130kmh much faster on 2nd gear alone (NB mine is the 4spd AT). I'm very pleased with the low-torque gains on the Autoexe - finally i have that slight 'lurch' from start which the manuals seem to have, but the ATs don't. The Autoexe starts off idle with a really low, bassy growl. When first installed, it was barely audible, but sounds louder now. In time, the db will increase to an extent. On higher RPM revs, exhaust sounds deep and wet, and def not those shrilly Remus' we hear on the expressways from time to time. Installation was a breeze, and took under an hour at Monster Garage at Ubi, who's the only authorized dealer in Singapore, so these guys know their stuff. The torque/hp improvement was a shocker esp on low end, esp when mine's an AT. I've heard of bros installing Fujitsubos and HKSs that have either no or negative benefit. In this respect, I'm mighty pleased with the Autoexe. Sound is not loud, but a soft low bassy growl when idle, which develops into a mature wet sound at higher revs.

RE-AMEMIYA Additional RHS Oil Cooler for Mazda RX8 (Series 1, 2003-2008) RE-AMEMIYA Additional RHS Oil Cooler for Mazda RX8 (Series 1, 2003-2008)

I have the oil cooler fitted recently Jarl, with a MazdaSpeed (RHS) oil cooler Try to get the MazdaSpeed or the US, Hong Kong or Japan spare parts. I suspect they are different but what the hell it is still an oil cooler. Japan does not have oil cooler in the Type S as standard but most people will have that as option. Certainly they mostly opted for the MazdaSpeed version of the oil cooler (btw it looks the same as the other one I have now ) There are many oil cooler available as an aftermarkey option, such as HKS and Fujita engineering, just to name two. They are very pricey and go over the $1000 mark. So I choose the $600 MazdaSpeed one instead. What you need is a garage, really. I will recommend changing oil and oil filter at the same time. It does mean a cleaner job. Make sure you take care of the joints and prepare for an oil leak (did have some on my installation). The right oil cooler gets the first of the oil from the central (engine) side and they travel to the left (stock) one before going back to central. There is a bass tube (as shown in the attachement above) to connect the right to the left oil cooler. Get a quote for $300 installation since it will take someone 6 hours to do (inc changing oil). Make sure they run the car for 10 minutes before putting the front bumper back up, just to see if there are still leaks. Result is amazing, central console is not hot anymore, well... it is cooler than what it has been. Say the temp in the cup holder used to be like the upper tray of the coffee machine (the area that warms the cup). Now it is like the keyboard of your laptop, still warm but certainly the house key I put in the cup holder will not burn my finger anymore. MazdaSpeed oil cooler is race proven. In BestMotoring, people raced for 20 minutes in the heat, MazdaSpeed oil cooler has a oil temp of 100 degree cel, but the S2K and Integra are running at 130 degree plus.

One of the nicest guys to deal with as well for parts and knowledge on Mazdas is next level !

The rotary engine is acutely sensitive to everything happening between the airbox and the throttle body. Dirty filtration, a degraded MAF sensor or a weeping hose all show up immediately in idle quality, and throttle response and fuel economy suffer as a result. The Mazda RX8 intake parts listed here span the full inlet path, address a single failed component or plan a considered upgrade without hunting across multiple suppliers.

Replacement and service items for the RX8 intake tract

Routine maintenance of the RX8 air intake starts with the filter and works outward. A fresh RX8 performance air filter restores filtration efficiency and keeps abrasive particulates away from the apex seals, a consideration that matters more on a rotary than on a piston engine. Hoses and ducting harden and crack with age, and an RX8 intake suction kit addresses these in one go rather than chasing individual splits.

Sensors and solenoids are equally important across the range of RX8 intake parts. The MAF sensor governs fuelling across the entire rev range, and a reading that has drifted even slightly will skew the fuel map, blunting response across the board.

If you are sourcing an RX8 MAF sensor for an Australian-specification car, confirm the part against your Series fitment before ordering. An RX8 intake solenoid replacement is worth investigating whenever idle hunting or fault codes point toward the intake control circuit.

Mazda RX8 intake parts for a rotary build

Owners planning upgrades beyond a like-for-like swap have several directions available depending on the build brief:

  • An RX8 cold air intake kit repositions the inlet point to draw from a cooler area of the engine bay, which is particularly relevant because heat-soak around a rotary is significant.
  • A Mazda RX8 ram air intake arrangement maximises inlet velocity and can complement other breathing modifications in a more developed build.
  • Upgraded intake hoses and couplers tighten up a system opened by filter or piping changes, keeping vacuum figures consistent on forced-induction builds.

Plan the intake system as a complete path

The filter, inlet pipe, hoses, sensors and solenoids all interact. Replacing one worn component while leaving a cracked hose in place limits the benefit of the new part and can make diagnosis harder next time a fault appears.

When working through the full set of Mazda RX8 intake parts, inspect each section of the tract while it is accessible and replace hardware that is marginal rather than waiting for a confirmed failure. That approach keeps the inlet system honest and the rotary running as it should. For official Mazda vehicle and owner information, visit Mazda Australia.

Frequently Asked Questions

What intake parts are available for the Mazda RX8?

The RX8 intake range covers the full air path, including performance air filters, ram air and cold air intake kits, intake suction hose and ducting kits, mass air flow (MAF) sensors, intake solenoids and associated mounting hardware. This means you can address a single worn item or refresh the entire intake system in one order.

How do I know which intake component is causing a fault on my RX8?

Not every intake issue starts with the filter or pipework. When diagnosing an intake-related fault on an RX8, also inspect the MAF sensor and intake solenoid, as these control components are common sources of problems. Identifying the specific failed part before ordering helps avoid replacing one item while leaving another questionable component in place.

What is an RX8 intake suction kit and do I need one?

An RX8 intake suction kit addresses the hoses and ducting within the intake tract rather than the filter or sensors alone. Over time these hoses can crack, collapse or develop air leaks that upset fuelling and idle quality. If your ducting shows signs of age or damage, replacing it as part of an intake refresh is worthwhile.

Can I fit a cold air intake or ram air intake to my RX8?

Yes. Cold air intake and ram air intake kits are available for the RX8 and suit owners who want a revised inlet arrangement as part of a more focused intake setup. Check each product listing carefully to confirm the kit suits your specific RX8 application before ordering.

Should I replace the MAF sensor at the same time as other intake parts?

If you are already disturbing the intake tract for a filter change or hose replacement, it is a good opportunity to inspect the MAF sensor. A worn or contaminated MAF sensor can cause rough running and poor throttle response on the RX8, so replacing it while access is clear avoids repeat disassembly later.

Is it worth replacing multiple intake components at once rather than just one part?

Yes, approaching the intake as a system rather than replacing a single component in isolation is generally more effective. While you have access to the intake tract, inspecting and replacing worn hoses, sensors and hardware alongside the primary part produces a tidier, more reliable result and reduces the chance of a related fault appearing shortly after.

How do I confirm an RX8 intake part is the right one for my car before buying?

Check the individual product listing for its stated application, and compare the part with the unit currently fitted to your car. The RX8 was produced in Series 1 and Series 2 variants, and some intake components differ between them, so confirming the correct application before ordering is important.
