TRQ Ignition Kit Ignition Coil Spark Plugs Compatible with 1991-1993

In this review the TRQ Ignition Kit is evaluated for owners of early 1990s BMW 318i and 318is who need a complete ignition service in one purchase. The kit includes four ignition coils and four spark plugs and is marketed as a direct fit OE replacement, so the single biggest reason to buy is convenience: it replaces the full ignition pack with parts matched to stock specifications and multiple OE reference numbers for direct swap installation. Expect a straightforward repair if compatibility is confirmed for the model years listed.

Key Features

• Complete 8-piece kit: Includes four ignition coils and four spark plugs so a full-cylinder ignition service can be completed in one visit without sourcing separate parts.
• Direct fit OE replacement: Designed to match factory dimensions and mounting points so no modifications are needed for the specified BMW 318i/318is years.
• Application specific design: Built to fit the 1991-1993 BMW 318i and 318is models, reducing fitment guesswork when the vehicle match is confirmed.
• Tested for performance: TRQ states fit, lab, and road testing to meet heat range and life cycle expectations similar to stock units.
• Reference compatibility: Supplied with many OE and aftermarket reference numbers to help cross-check fitment against factory part lists.

Who It's For

This kit is best for DIY mechanics and independent shops working on 1991-1993 BMW 318i or 318is cars that need a full ignition coil and spark plug replacement. It suits owners who prefer to replace all ignition components at once to restore consistent firing across all cylinders and reduce future troubleshooting.

Those who should look elsewhere include drivers with later model BMWs or vehicles outside the listed years, and anyone requiring OEM-branded parts with guaranteed original manufacturer warranty coverage; also consider higher-end coils if long-term lifespan concerns are the top priority.
