TRQ Ignition Coil Set Compatible with 2003-2015 Toyota V6 - Improved

In this review of the TRQ Ignition Coil Set, the verdict is practical: this kit is aimed at DIY owners and mechanics who need a direct-fit replacement for 4.0L V6 Toyotas. The six-piece set replaces the original coils on compatible 2003-2015 Tacoma, Tundra and 4Runner models and delivers noticeable improvements in throttle response and smoothness. The biggest reason to buy is the combination of direct-fit design and performance-focused construction, which makes installation straightforward and often restores engine feel without expensive dealer parts.

Key Features

• Complete 6-piece kit: Includes six performance ignition coils so the entire bank can be replaced at once for consistent firing and balanced engine operation.
• Direct-fit replacement: Pre-assembled components are designed to match original equipment dimensions, reducing installation time and eliminating modification.
• Enhanced energy transfer: Up to an estimated 15% more energy transferred to the spark plugs, which helps with combustion efficiency and throttle response.
• High temperature epoxy: The coils use epoxy rated for elevated engine temperatures to extend service life under normal conditions.
• Reference compatibility numbers: Supplied with common reference numbers to help confirm fitment for the listed Toyota models and years.
• DIY support resources: Backed by a large library of DIY videos intended to help users view the job before they do it, making the swap easier for non-professional installers.

Who It's For

The TRQ ignition coil set is best for owners of 2003-2009 Toyota 4Runner, 2005-2015 Tacoma and 2005-2011 Tundra V6 4.0L who want an affordable, full-bank replacement that improves throttle response and smoothness. It suits DIYers who value direct-fit parts and step-by-step video guidance to complete the swap at home.

Those who need original equipment manufacturer lifetime service expectations or who have experienced repeated short-term coil failures may prefer to consider alternative brands with longer field-proven durability. If a single coil failure is the issue, replacing only the failed unit could be more economical than a full kit for some owners.

Pros & Cons

Pros

• Good fit and straightforward installation thanks to direct-fit construction and pre-assembled components.
• Improves throttle response and engine smoothness by delivering more energy to the spark plugs.
