High under hood temperatures on Jaguars, especially the V12’s, cause spark plug wire deterioration over time, resulting in reduced engine performance. Regular replacement of spark plug wires is highly recommended but pricey with list prices of well over $100.00 and in some cases exceeding $200.00. At v12performance we've addressed the problem with the PowerCat line of high quality yet affordable spark plug wire sets designed specifically for Jaguars that meet or beat both OEM and aftermarket sets in performance and quality of construction.

Made in the USA exclusively for V12 Performance to our specifications by a leading automotive wire manufacturer, PowerCat wires ensure ignition cycle precision, optimize engine performance and enhance fuel efficiency. PowerCat wires are designed to bring out the best in your Jaguar. Using only top quality materials, PowerCat wires are tough, with a temperature rating between -100F and 450F, stainless steel snap lock, positive fit terminals and 100% silicone boots that are both waterproof and highly resistant to corrosion/vibration/heat. Every 8mm wire is fully tested and inspected and features a Kevlar/Glass fiber core with spirally wound wire rated at 850 Ohms/foot. “Electronics friendly” shielding protects onboard computers, engine management and other sensitive systems from EFI and EMI.

PowerCat spark plug wire sets are available for all Jaguar models including XJS, XJ6 Series I, II & III, E type and XJ6 (XJ40) in black, blue, red and yellow. They are labeled by cylinder number for easy identification and include dielectric grease for smooth installation (and removal if necessary). Treat your car right with outstanding wires at a great price (from $59.00) with v12performance PowerCat wires.

We also offer complete tune up kits for both Marelli and Lucas ignition XJS cars.
