Pindex UF230 8 Pack Ignition Coils and Iridium Plugs - Reliable

In this review the Pindex UF230 8 pack ignition coils paired with 4504/PK20TT iridium spark plugs are judged as a straightforward, cost-conscious replacement for older Toyota and Lexus V8 engines. The set is aimed at owners of 4.3L and 4.7L Toyota/Lexus models who need a full ignition refresh; the single biggest reason to buy is the complete kit format that replaces all coils and plugs at once, reducing install time and ensuring matched components. The reviewer found the kit to deliver solid build materials and easy installation on compatible vehicles.

Key Features

• Vehicle Compatibility: Covers a wide range of Toyota and Lexus models and years so owners of 4Runner, Tundra, Land Cruiser, Sequoia, LS430, GS430, SC430, GX470 and LX470 can confirm fit before buying.
• Complete Kit: Includes 8 UF230 ignition coils and 8 4504/PK20TT iridium spark plugs plus a user manual, which simplifies doing a full-bank service in one visit.
• Durable Construction: Coils use high quality isolating epoxy, imported copper wire and a specialized steel core for improved vibration and shock resistance in demanding engine bays.
• High-Temperature Components: Silicone boots rated to 550 degrees and 40,000 V insulation aim to provide reliable performance under thermal and electrical stress.
• OEM Cross References: Compatible with common OEM part numbers such as IC573, UF-230 and 90080-19027 so buyers can match to factory replacements.

Who It's For

This kit is suited for DIY mechanics and independent shops working on Toyota and Lexus V8 engines from the early 2000s who want a matched set of coils and iridium plugs to restore ignition performance. It is particularly useful when multiple misfires or age-related failures indicate replacing the whole bank rather than individual parts.

Shoppers with newer vehicles or models outside the listed year ranges should look elsewhere or verify the coil pack pin count and OEM part numbers first, since ignition components can differ by manufacture month and engine revision.
