R35 Coil Conversion Kit — RB26

The R35 coil conversion kit — six modern R35 GT-R ignition coils onto an RB26, with reinforced harness, adapters and no ECU retune.

Brand: Garage Yoshida
Product Name: R35 Coil Conversion Kit
Fitment: RB26DETT-powered Skyline GT-R (R32 / R33 / R34; BNR34-specific variant available separately)
Kit Contents: Six R35 GT-R ignition coils, mounting adapters, reinforced wiring harness with direct-battery feed
Coils: Six × R35 GT-R ignition coils (built-in power transistors)

Note: Plug covers require minor cutting but mount identically to the standard covers. No ECU tuning required as a like-for-like repair or foundational upgrade. Multiple test vehicles have confirmed the improvement.

R35 ignition coils are simply better coils than the ones the RB26 shipped with — longer spark duration, revised wire construction, and the transistor built in rather than sat separately. This kit is what makes them bolt on: correct adapters, a reinforced harness fed directly from the battery, and a plug-cover approach that keeps the top of the engine looking factory. Cheaper than a set of OEM RB26 coils, and a genuine step forward rather than a like-for-like.

Features:

• R35 Coils: Six modern GT-R ignition coils with longer spark duration and revised wire construction.
• Built-in Power Transistors: No separate transistor module, unlike the OEM RB26 setup.
• Reinforced Harness: Direct-battery feed included for a clean, high-current supply.
• No Retune Required: Works as a repair-grade upgrade without an ECU rewrite.
• OEM-Style Fit: Plug covers mount identically to standard once trimmed.

For RB26 owners chasing a real ignition upgrade rather than paying OEM prices for the coils the engine left the factory with.
