Pro Tune-Up Kit | 2RZ & 3RZ

"Ultimate" Ignition Tune-Up Kit

Elevate your engine's reliability and ignition efficiency with the LC Engineering Pro Tune-Up Kit. Specifically curated for the "waste-spark" ignition systems found on 1998–2000 Toyota 2.4L and 2.7L engines, this kit replaces aging factory components with high-performance alternatives designed to withstand the rigors of both daily driving and off-road use.

By combining industry-leading Magnecor race wires with precision-engineered NGK plugs, this kit ensures a stronger, more consistent spark. This leads to smoother idling, improved throttle response, and more efficient combustion—making it the definitive maintenance upgrade for the 2RZ and 3RZ platforms.

Kit Components & Specifications

• Magnecor 8.5mm KV85 Competition Spark Plug Wires:

These aren't your standard auto-parts store wires. Magnecor’s 8.5mm wires feature a proprietary metallic inductance EMI suppressed conductor. This design provides maximum spark energy to the plugs while protecting your vehicle’s sensitive electronics from RFI and EMI interference. The high-heat silicone jackets are built to resist extreme under-hood temperatures without cracking or degrading.

• NGK Performance Spark Plugs (Set of 4):

We include a full set of NGK plugs, the gold standard for Toyota engines. To ensure the perfect match for your specific build, we offer multiple heat ranges. Whether you are running a bone-stock daily driver or a high-compression performance engine, you can select the plug that best suits your needs.

Technical Fitment Notes

• Coil Pack Ignition Only: This kit is designed exclusively for the "Late" 1998–2000 2RZ and 3RZ engines that utilize external coil packs (mounted on the side of the engine).
• Compatibility Restrictions: NOT for early models equipped with a distributor. NOT for later models (2001+) that utilize Coil-on-Plug (COP) ignition systems.
• Heat Range Selection: If you are unsure which heat range to choose for your application, please contact our technical support team for a recommendation based on your engine's modifications.

Question: What is the correct spark plug gap for my Toyota engine?

-For 2000 and earlier Toyota models, the spark plugs should be gapped to 0.031".
