TRQ Ignition Kit Ignition Coil Spark Plugs for 2011-2012 Subaru

In this review of the TRQ Ignition Kit, the bottom line is simple: it is a practical, budget-conscious replacement for owners of 2011-2012 Subaru Forester 2.5L and 2012 Impreza 2.0L who need a full ignition refresh. The kit includes four ignition coils and four iridium spark plugs, delivering a complete eight-piece repair that restores like-new ignition parts without complicated modifications. It is best chosen for drivers wanting a direct replacement that matches stock fit and basic performance, though longevity concerns mean those wanting maximum durability may want to consider higher-end options.

Key Features

• Complete 8-piece kit: Includes four ignition coils and four iridium spark plugs to replace the entire ignition set in one service visit.
• Direct replacement coils: Coils are application specific and designed to install without modifications, saving time at the garage.
• Iridium spark plugs: The iridium plugs aim to match factory heat range and combustion characteristics for consistent ignition and engine response.
• Tested to match stock: Fit, lab, and road tested to meet the original equipment specifications for fit and basic performance restoration.
• Warranty coverage: Backed by a 2-year / 24,000-mile parts-only warranty for replacement of defective products within the coverage window.

Who It's For

This kit is aimed at Subaru owners who need a full ignition system refresh and prefer the convenience of replacing all coils and plugs at once. It is particularly useful for DIY mechanics and independent shops working on 2011-12 Forester H4 2.5L and 2012 Impreza H4 2.0L engines where direct-fit parts reduce install time.

Not ideal for drivers seeking long-term premium durability or who cannot tolerate any early failures; several user reports cite coils failing within months, so those prioritizing longevity or gap precision may want OEM or higher-tier aftermarket options instead.
