Ignition Coil and Iridium Spark Plugs for Lotus Elise (2004-2011) 1.8L

Direct-Fit Ignition Coil and Iridium Spark Plug Kit for 2004-2011 Lotus Elise

Direct-Fit Ignition Overhaul: Restores high-RPM spark energy and eliminates high-load misfires across the rev range on 1.8L Toyota-powered Lotus Elise models.

The Stock Elise High-RPM Heat Soak & Breakdown Issue

The mid-engine configuration of the Series 2 Elise creates a tight, thermally punishing environment where trapped heat degrades ignition components. Under prolonged track sessions and high-cam VVTL-i operation above 6,200 RPM, factory ignition coils suffer dielectric breakdown and thermal fatigue within their primary windings. Simultaneously, worn spark plug gaps increase the electrical resistance required to jump the spark gap, leading to cylinder misfires, sluggish throttle response during cam changeover, and loss of top-end power.

The Engineering Solution

This complete ignition kit utilizes heavy-duty coil-on-plug units wound with high-conductivity oxygen-free copper and insulated with high-grade dielectric epoxy to isolate against engine bay heat soak. Matched with four fine-wire iridium spark plugs, this setup reduces the required firing voltage, provides high thermal resistance against fouling, and delivers a stable flame kernel past the 8,500 RPM rev limit. Direct-fit blade terminals and factory-keyed connectors ensure seamless integration with the OEM harness.
