FILTERUP LS spark plug wire set 8pc 9070C Ceramic Boot — extreme-heat, OE-length for GM LS3/LS4/LS7/LT engines

FILTERUP 8-piece LS spark plug wire set with 9070C ceramic boots delivers high-heat resistance and direct-fit compatibility for many GM LS-series engines.

Designed for tight engine bays and high-temperature applications, this FILTERUP wire kit replaces factory wires on a range of Cadillac, Chevy and GMC models that use LS-style terminals. The set pairs high-dielectric ceramic boots rated for extreme heat with OE-length wires and a direct-fit design to maintain proper routing and reliable spark delivery while reducing the risk of melted boots or crossfire in performance and everyday vehicles.

Which vehicles and engines does this wire set fit?

The FILTERUP 9070C kit is built for GM models that use LS terminals and common LS-series engines. It covers many years and trims across Cadillac, Chevrolet and GMC; always verify fitment against your VIN or engine code before purchase.

• Compatible families: LS3, LS4, LS7, LT-series engines
• Notable fitments: Cadillac CTS (2006–2007), Chevy Corvette (2005–2008), Silverado and Sierra (2007–2008 ranges)
• Check the main image and part number 9070C for exact vehicle match

How do the ceramic boots help under extreme heat?

These wires use an extreme-heat ceramic boot design intended to withstand temperatures far above typical silicone boots to help prevent melting near headers, turbochargers or restrictive manifolds. That improved heat tolerance helps maintain insulation and a reliable spark path where other boots can fail.

• Ceramic boots rated for very high temperatures to resist melting
• Better dielectric strength near exhaust components and tight manifolds
• Reduced risk of arcing and misfire from compromised boot insulation

What performance and installation benefits can I expect?

The kit is made as a straight replacement for factory-length wires and LS terminals, which simplifies installation and keeps original routing. Performance-wise, you get consistent spark delivery under load and heat, plus wires designed to resist abrasion and vibration in the engine bay.

• OE-length wires for correct routing and secure connections
• Durable construction to withstand engine bay vibration and wear
• Maintains consistent resistance and spark conduction under stress

What warranty and support does FILTERUP provide?

FILTERUP backs this spark plug wire set with a one-year product quality support period. If you suspect a defect or need fitment help, contact FILTERUP customer support for troubleshooting and replacement guidance.

• One-year product quality support included
• Customer service for fitment verification and issue resolution
• Part number to reference: 9070C for compatibility inquiries

Who is this for: This wire set is intended for owners and mechanics working on GM vehicles with LS-series or LT engines who need a direct-fit replacement that resists extreme under-hood heat—performance enthusiasts, track-day drivers, and anyone retrofitting headers or running tight-clearance manifolds where stock boots melt or fail. If you require OE routing, LS terminal compatibility, and higher heat tolerance than standard silicone boots, the FILTERUP 9070C 8-piece set is a strong aftermarket option.
