UF624 Ignition Coil & 97390 Double Iridium Spark Plug Set - Reliable

In this review the UF624 ignition coil and 97390 double iridium spark plug kit is judged as a practical replacement pack for owners of select Acura and Honda V6 models. The set includes six ignition coil packs and six double iridium spark plugs and is aimed at drivers who need a straightforward swap to resolve misfires, rough idle, or poor fuel economy. The single biggest reason to buy is the matching-to-OE design that simplifies installation while promising more consistent spark and better cold-start performance.

Key Features

• Vehicle compatibility: Covers key V6 models including 2010-2013 Acura MDX 3.7L and 2013-2015 Acura RDX 3.5L so buyers can confirm fit before purchase.
• Complete kit: Includes six ignition coils and six double iridium spark plugs, providing all parts needed for a full bank replacement for most 3.5L and 3.7L applications.
• Improved cold-start: The double iridium spark plugs are designed for consistent ignition and better cold-start performance compared with worn factory plugs.
• Durable coil construction: Coils use a stainless-steel spring, ferrite noise suppressor, and thermoplastic connector to resist heat cycling and reduce radio frequency interference.
• OE cross-reference: Matches OE numbers such as 30520-RN0-A01 and common replacement codes, easing part identification during purchase.
• After-sales support: Manufacturer offers 24 hour customer service and a 1 year product service period for installation or quality questions.

Who It's For

This kit is best for owners of compatible Acura MDX, RDX, ZDX and Honda Pilot or Ridgeline models who are experiencing misfires, decreased power, rough idle, or reduced fuel economy and want an all-in-one replacement that mirrors OE fit. It also suits DIY mechanics who want a full-bank kit to complete a single service visit without sourcing individual parts.

It is less appropriate for vehicles outside the listed model years or for owners who prefer OEM branded parts from a dealership; buyers should check the second main product image and the OE reference numbers to confirm compatibility before ordering.
