Mazda RX-8 2004 Parts Catalog

You’ve got a 2004 RX-8 sitting on jack stands because the replacement bumper cover you ordered doesn’t fit. The aftermarket catalog listed it as compatible, but the mounting tabs are off. Sound familiar? Stop wasting time. Get the factory-issued parts catalog. The Mazda RX-8 2004 Parts Catalog is 15 pages of OEM part numbers with suffixes that tell you exactly which revision fits your VIN. No cross-referencing, no returns.

What’s Inside the 15-Page Parts Catalog

Flip to the SECTION INDEX and you’ll see 46 sections covering everything from A/C/HEATER/VENTILATION to WINDSHIELD. Each section has an exploded diagram with numbered callouts. For example, the FRONT BUMPER section lists the cover, emblem, clips, retainers, absorber, reinforcement bar – each with a factory part number like FE01-50-031C for the bumper cover with headlamp washers, or FE01-50-031D without. The catalog also notes paint-to-match parts. That detail is why OEM catalogs beat aftermarket databases.

That level of precision prevents ordering the wrong part.

ABS/Brakes and Cooling – Don’t Guess the Part Number

The ABS/BRAKES section covers the entire hydraulic system, including sensors, calipers, and the control module. For cooling, you get the radiator, hoses, and the engine oil cooler – with separate part numbers for manual and automatic transmissions. Using the wrong ABS sensor can trigger a dash light or fail a safety inspection. The factory catalog gives you the exact revision, like R134a refrigerant capacities listed under A/C REFRIGERANT CAPACITIES. Safety depends on getting this right, especially on a car with a Renesis engine that runs hot.

Fuel System and Exhaust – OEM vs Aftermarket

Under FUEL TANK you’ll find the filler neck, pump, and vent lines. The EXHAUST section lists the manifold, catalytic converter, and muffler. Aftermarket catalogs often lump together 2004-2008 models, but the factory catalog separates by year and even by automatic vs manual transmission. For example, the front bumper lists a different oil cooler duct for manual and automatic (part N3K2-14-708A vs N3K1-14-708A). If you just order a generic “fits RX-8” part, you’ll waste a Saturday. Use the factory part numbers to order exactly what left the Hiroshima assembly line.

Engine, Suspension, and Electrical – Why OEM Part Numbers Matter

Inside the ENGINE/TRANS section you see motor mounts, oil cooler, and under-cover shields. The FRONT SUSPENSION and REAR SUSPENSION sections include control arms, bushings, and struts. The ELECTRICAL section lists the alternator, starter, wiring harness connectors, and battery terminals. A wrong engine mount can transmit vibration into the cabin. A wrong electrical connector can short the ECU. The catalog even includes the Automotive Industry Overview [LINK_ID_EXT_0: Automotive Industry Overview] context for component sourcing. For battery replacement, refer to the Automotive Battery [LINK_ID_EXT_1: Automotive Battery] section in the electrical category. Every part number is traceable to Mazda’s engineering release.

How to Use This Catalog with Service Manuals

This parts catalog is designed to work alongside a service manual. Once you’ve identified the correct part number from this book, use a workshop manual for torque specs and removal procedures. For the Renesis engine rebuild, pair it with the LINK_ID_REL_2: Mazda RX-8 Y16M-D 2003 Workshop Manual – Transmission Rebuild. For wiring diagnostics, add the LINK_ID_REL_1: Mazda RX-8 Electrical Schematic. And for updated procedures on later models, the LINK_ID_REL_0: Mazda RX-8 2008 Service Highlights covers changes through 2008. Together, you have a complete system for repairing and maintaining your RX-8.

Frequently Asked Questions

Does this catalog include torque specifications?

No. This is a parts catalog, not a service manual. It only lists part numbers.

Can I use this to identify parts for a 2004 RX-8 with the Renesis engine?

Yes. The 2004 RX-8 came exclusively with the 13B-MSP Renesis. The catalog covers every factory component for that engine, including engine oil cooler, engine under cover, and transmission mounts. However, always cross-reference with your VIN because mid-year production changes occurred. For example, the front bumper cover changed depending on headlamp washer option – the catalog clearly marks those variants.

How are part numbers organized? Are there illustrations?

Each section has exploded diagrams with numbered callouts. For example, on page 1 (035-04134) the rear bumper section shows the cover, dam, bracket, absorber, reinforcement bar, and protector – each with a part number like FD01-50-221B. The illustrations are line drawings, not photos, but they clearly indicate which fastener goes where. The section index at the back gives page numbers for every component group.

I have a 2004 RX-8 with automatic transmission. Will the catalog list both auto and manual parts?

Yes. The catalog distinguishes between automatic and manual transmission parts in many sections. In the front bumper area, you’ll see separate part numbers for the oil cooler duct for auto vs manual, labeled ‘Auto Trans’ in the part list. Similarly, the engine/trans mounts and exhaust sections differentiate between the two. Always check the notes next to the part number before ordering.
