OKLPF Ignition Coil Pack with Iridium-Platinum Spark Plugs — 4-Piece Kit for 1.8L L4 (UF247), Direct-Fit Durability

OKLPF 4-piece ignition coil pack UF247 paired with iridium-platinum spark plugs is a direct-fit replacement kit designed to restore reliable spark and improve combustion for 1.8L L4 engines in select Toyota and GM models.

This kit combines four high-performance ignition coils built with premium materials and four long-life iridium-platinum spark plugs engineered for precise sparks and thermal resistance. It replaces OE part UF247 and related numbers for a plug-and-play swap on compatible Chevrolet Prizm, Pontiac Vibe, Toyota Celica, MR2 Spyder, Corolla, and Matrix 1.8L engines. The components are manufactured to match OEM specifications so they install without modification and aim to reduce misfires, support steadier idling, and help maintain fuel efficiency.

How does this kit improve engine starting and running stability?

The coil packs use high-purity copper windings and a silicon steel core to deliver consistent high-voltage output while the iridium-platinum plugs focus that energy into stronger, more reliable sparks. Together they reduce the chance of weak ignition events that cause rough starts or stumbling during acceleration.

• High-temperature epoxy resins resist breakdown under heat stress.
• German-imported copper windings for stable current transfer.
• 360° laser-welded center electrode on plugs for focused spark.
• Direct-fit design replaces UF247 and equivalent OE numbers.

Will these parts fit my car and are they easy to install?

This kit is designed for direct compatibility with 1.8L L4 applications listed by the manufacturer; always confirm fitment using your vehicle year, make, model, and engine size. Because the coils and plugs match OEM dimensions, most owners or technicians can install them using standard hand tools in a straightforward swap.

• Compatible models: Chevrolet Prizm (1999–2002), Pontiac Vibe (2003–2008), Toyota Celica, MR2 Spyder, Corolla, Matrix (various 1999–2008 years).
• Direct plug-and-play replacement—no custom wiring or adapters required.
• Typical install: remove old coil packs and plugs, fit new plugs, connect coils, torque to spec.
• Check "amazonconfirmedfit" or fitment guide before purchase to ensure correct match.

What materials and design features make these parts durable?

The coil pack construction uses quality materials chosen for longevity: corrosion-resistant copper, a silicon steel core for magnetic stability, and high-temp epoxy to protect internal windings. The spark plugs use a high-alumina ceramic insulator and a platinum-rich electrode for extended service life under thermal cycling and combustion stresses.

• Coil: anti-oxidation coatings and high-temperature resin encapsulation.
• Plug: 90% platinum content and 95% alumina ceramic for heat resistance.
• Welding and cold extrusion techniques for long-lasting electrode attachment.
• Estimated spark plug life: tens of thousands of miles under normal use.

Who is this for? This OKLPF kit is aimed at DIY vehicle owners and mechanics who need a reliable, OEM-compatible ignition coil and spark plug replacement for the listed 1.8L engines. It's a good choice if your vehicle shows intermittent misfires, rough idle, reduced fuel economy, or if you are performing scheduled maintenance and want longer-lasting plugs combined with robust ignition coils. Choose this set when you want straightforward installation, OEM fitment, and materials designed to resist heat and corrosion without extensive modification.
