TICANEE Iridium Spark Plugs & Wires Kit for Chevy/GMC 4.8L–6.0L V8 – Direct Fit, Dual Iridium

If you drive a Chevrolet Silverado, Tahoe, Suburban, Avalanche, or a GMC Yukon/Sierra from the late 2000s to early 2010s, this kit is built to match OE fitment and simplify installation. The set replaces OE numbers 41-110 and 12621258 and arrives plug-and-play so you can swap components without modification. It combines dual-iridium electrodes, a copper core, and a quenching suppressor seal to balance long service life with consistent ignition characteristics.

Will these spark plugs and wires fit my Chevy 5.3L or 6.0L engine?

Yes — the TICANEE kit is manufactured as a direct replacement for the referenced GM OE part numbers. It is compatible with a broad list of Chevrolet and GMC models from 2007–2014 that use those OE numbers.

• Direct-fit for OE 41-110 and 12621258 — no adapters needed.
• Compatible models include Silverado 1500/2500/3500, Tahoe, Suburban, Avalanche, Caprice, Colorado, Corvette, and Express vans within specified years.
• Designed for 4.8L, 5.3L and 6.0L V8 engine families common in those vehicles.

How long do the iridium plugs last and what materials are used?

These plugs use dual iridium on the center electrode and an iridium pad for the ground, which reduces electrode wear and helps maintain spark quality over time. A pure copper core aids heat transfer while the integral suppressor seal helps protect against interference and compression leakage.

• Dual-iridium electrode design for extended service life.
• Pure copper core for controlled electrode temperature and fouling resistance.
• Kernel quenching suppressor seal to lower radio-frequency interference and improve sealing.
• Rated for up to 100,000 miles of service under normal operating conditions.

Will replacing my plugs and wires with this kit change performance or fuel use?

Replacing worn plugs and degraded wires restores consistent ignition timing and spark energy, which supports smoother combustion and engine response. While no product can guarantee a specific MPG increase, properly functioning ignition components help the engine run as intended and can reduce misfires and rough idling.

• Restores consistent spark delivery for smoother idle and acceleration.
• Reduces ignition misfires that can negatively affect drivability.
• May support improved combustion efficiency when replacing worn OEM parts.

What warranty and quality controls come with the set?

TICANEE backs this ignition kit with a 24-month warranty and applies quality checks during manufacturing to ensure fitment and material integrity. The company highlights workmanship inspection and post-production testing as part of its quality process.

• 24 months warranty for defects and workmanship concerns.
• Quality control procedures to verify fit and finish before shipping.

Who is this for: The TICANEE Iridium Spark Plugs and Wires Set is intended for owners and technicians servicing GM 4.8L, 5.3L and 6.0L vehicles from model years roughly 2007–2014 who need a reliable, direct-replacement ignition kit. It suits DIY mechanics who want plug-and-play components and professional shops that require OE-compatible parts with extended service life and factory-style fitment.
