How do the GBTAD coils and plugs improve performance?

GBTAD designs coils with aerospace-grade copper windings and high-density epoxy for stable conductivity and heat resistance. When paired with matched spark plugs, they reduce misfires and improve combustion consistency—helpful for driveability and throttle response.

• Higher conductivity reduces energy loss between coil and plug
• Epoxy sealing protects internal windings from vibration and moisture
• Matched plug-gap and coil output for consistent sparks across cylinders
• Manufacturer claims up to an 18% ignition performance improvement in controlled tests

What’s included and what parts are replaced during installation?

This kit groups ignition and sealing components to cover common causes of poor ignition and oil leaks around the valve cover. Replacing these items together reduces repeat labor and helps ensure a complete repair.

• Full set of GBTAD ignition coil packs (quantity to match engine cylinders)
• Matched spark plugs sized and gapped for 1.4L turbo applications
• Engine valve cover gaskets plus necessary bolts
• Replacement oil filler cap to restore proper sealing

Is installation difficult and what should I expect?

Installation is a moderate DIY job for anyone comfortable removing the engine cover and valve cover components; otherwise a professional mechanic can fit the kit in about 1–2 hours. Always torque bolts to OEM specs and check for vacuum or wiring clips that secure coil packs.

• Basic hand tools and torque wrench required
• Inspect cylinder head mating surfaces before gasket installation
• Replace spark plugs one at a time to maintain firing order
• Clear any stored codes after installation and road-test for improvement

Who is this kit for? This GBTAD kit suits owners and independent shops working on GM 1.4L turbo engines who want a single-purchase solution for ignition faults and valve-cover leaks. It’s ideal if you need matched coils and plugs plus the valve-cover sealing hardware to avoid repeated labor. If you’re verifying fitment, check the supplied part numbers and your vehicle’s engine code; contact GBTAD support for fitment help or warranty service.
