TRQ Iridium Spark Plugs 24 Piece Tune Up Kit - Direct Fit for V12

In this review the TRQ Iridium Spark Plugs 24 piece tune up kit is assessed for owners of V12 Mercedes vehicles who need a full replacement set. The bottom line: this kit is best for drivers who want a direct fit, OE replacement style spark plug set that covers many S, SL, CL and Maybach V12 models and arrives as a complete 24 piece kit so a full engine service is ready to go. The review focuses on fitment, build quality and the real-world effects on fuel use and driveability after installation.

Key Features

• Direct Fit: The plugs are designed as OE replacement parts so installation is straightforward and requires no adapter or special modification.
• Complete 24 Piece Kit: The package includes 24 spark plugs, allowing a complete tune up of V12 engines without buying additional pieces.
• Wide Vehicle Compatibility: Fitment covers many Mercedes V12 applications including S600, S65 AMG, SL600, SL65 AMG and CL600 across model years listed in the product information.
• Iridium Tip Construction: The iridium element aims to provide reliable ignition and long service life compared with standard plugs.
• OE Reference Coverage: The kit references many OEM and aftermarket numbers so it is easier to match the plugs to older service records.

Who It's For

This kit is aimed at owners and independent technicians who maintain Mercedes-Benz V12 engines and prefer a full-service parts swap in one purchase. It is particularly useful for those who want an OE-style replacement set to restore consistent spark across all 12 cylinders in a single service session.

Drivers who have non-V12 engines, or who need single plugs for diagnostics, should look elsewhere. Also, if a vehicle requires a non-iridium specialty plug not listed among the OE references, confirm fitment before buying.

• Direct fit and OE replacement intent simplify installation and reduce fitment errors.

Cons

• Some users reported mixed performance and occasional driveability issues after installation, so results can vary by vehicle condition.
