Injector Dynamics Fuel Injectors for Mazda

• XDS fuel injectors for Mazda in 1050cc, 1300cc, 1750cc and 2600cc flow rates, 60mm body length
• RX-7 sets of 2 in 11mm and 14mm O-ring configurations to suit FB, FC and FD fuel rails
• RX-8 (SE3P) secondaries, sets of 2
• MX-5 sets of 4 covering NA/NB, with NC listed within a shared multi-application set
• IDF750 and F1250 in-line fuel filters, replacement elements, O-ring kits, mounts and bracket kits
• BPC100 brushless pump controllers, with or without the E5LM fuel pump
• Browse the full Injector Dynamics range, or other platforms such as Nissan, Toyota, Subaru and universal fitment

RX-7 listings are split by year and by O-ring size. Injector Dynamics covers RX-7 79-84, 85-86, 87-92 (FC) and 93-95 (FD), each available in 11mm and 14mm O-ring options, so check the O-ring size on your existing fuel rail and intake manifold before ordering. Injectors with the wrong O-ring size will not seat correctly.

The FD runs a staged injection system with primary and secondary injectors; many street and moderate track builds upgrade the primaries only, while higher-boost single-turbo and bridgeport builds may size up both. RX-8 fitment is secondaries only, listed as "RX-8 03-11 (Secondaries Only)" for the Renesis. MX-5 applications cover NA/NB (90-05) and NC (06-14) as four-injector sets. Rotary engines have a high BSFC and are unforgiving of poor fuelling, so accurate sizing and correct O-ring configuration matter.

Installation by a professional is recommended, and injectors should be commissioned with the supplied characterisation data loaded into your ECU. Every set ships with dynamic slope flow rates, dead time across voltage and pressure, and flow matching at multiple pulse widths, in a format suited to Haltech, Link, MoTeC, AEM Infinity and Microtech. On a rotary this matters more than on most engines, because the combustion cycle amplifies any dead time error.

Before installation, confirm the O-ring size and body length suit your fuel rail, and check that your fuel pump, filter and pressure regulator can support the new injector flow. All Injector Dynamics injectors are compatible with petrol, E85, E100 and methanol, with stainless internals intended for aggressive fuels.

Which RX-7 years and O-ring sizes are covered?
Injector Dynamics covers RX-7 79-84, 85-86, 87-92 (FC) and 93-95 (FD), each in 11mm and 14mm O-ring options. Confirm your O-ring size against your existing fuel rail before ordering.

Do I need primaries, secondaries or both for an FD?
The FD uses staged injection with primaries and secondaries. Many street and moderate track builds upgrade the primaries only, while larger single-turbo or bridgeport builds may size up both.

What does the RX-8 fitment include?
It is secondaries only, matching the Renesis staged injection layout. Select the "RX-8 03-11 (Secondaries Only)" or SE3P set of 2.

Are these injectors suitable for E85 and methanol?
Yes. All Injector Dynamics injectors are compatible with petrol, E85, E100 and methanol, and use stainless internals built for aggressive fuels.
