PRP IGN-35A Ignition Coil Kit to suit Honda F Series

The PRP IGN-35A Ignition Coil Kit for the Honda F-series is the next step up from our proven R35 coil kits. After more than a year of testing in a handful of 1000hp+ engines, the IGN-35A is now in full production across all of our supported platforms.

The IGN-35A delivers more than double the punch of a genuine R35 coil and is rated to 4000hp (in a 6-cylinder setup). Even in a 1000hp build, the results are impressive.

With full control over the coil housing design, we reworked the primary coil configuration so the current draw is ~20% more efficient than a regular IGN1A coil pack. That means the IGN-35A uses the R35 3-pin connector and works with our existing R35 coil harnesses without significant wiring upgrades, while delivering the more efficient, longer burn of the IGN1A – the most powerful smart coil we've tested.

Key Features

• IGN-35A smart coils with more than double the output of a genuine R35 coil, rated to 4000hp (6-cylinder setup)
• ~20% more efficient current draw than a regular IGN1A coil pack
• Uses the R35 3-pin connector, so it is compatible with PRP R35 coil harnesses
• Billet alloy anodised bracket positions every coil for easy, non-invasive access to the coil plugs and spark plugs
• Custom-height, one-piece silicone injection-moulded stalks seal the spark plug wells to prevent water pooling and misfires
• Custom springs come pre-fitted inside the stalks for fast installation, with no spring trimming required
• Optional bench-tested, motorsport-grade harness with high-temp Tefzel wire, crimp joins, OEM connectors and glue-lined heat-shrink
• Bolt kit included for the 4 ignition coils and billet bracket to head
• Lifetime warranty on all PRP products

Kit Contents

• Billet alloy anodised coil bracket
• 4x PRP IGN-35A ignition coils
• 4x one-piece silicone spark plug stalks with pre-fitted springs
• Bolt kit for the 4 coils and bracket to head
• Universal wiring loom (if selected)

Notes

• IGN-35A coils will NOT work with any OEM-style igniter delete. If your setup relies on an igniter delete, please contact us before purchasing.
• F-series engines (other than the S2000 F20C / F22C) were fitted with a distributor from factory, so an aftermarket ECU is essential on these engines.
• Keep dwell under 2.5ms. For big power, run separate power feeds from the battery or dual ECU/PDM channels, as these coils draw more current.
• Universal Loom is a wire-in harness for aftermarket ECUs. No Loom means no wiring is included – use your existing R35 loom or your own harness.
