Ignition Coil Pack UF749 and Iridium Spark Plugs 93501 Compatible

In this review the combination kit of four UF749 ignition coils and four 93501 iridium spark plugs is evaluated as a direct replacement package for certain Honda Civic and Fit models. The bottom line: this kit is aimed at owners who need a straightforward, cost-effective replacement to restore engine smoothness and starting reliability. After installation many users report improved idle stability and crisper acceleration, and the pack addresses common symptoms like rough idle, hard starts, and reduced fuel economy when original coils or plugs have worn past roughly 80,000 km.

Key Features

• Model compatibility: The kit is specified for Honda Civic 2016-2020 2.0L and Fit 2015-2019 1.5L, helping buyers match parts to their engine without guesswork.
• Coil construction: Ignition coils use silicon steel, Japan-imported rubber, and Germany-imported varnished wire for improved durability compared with basic coils.
• Spark plug technology: Iridium electrode and engineered ceramic are chosen to deliver quicker starts and more consistent combustion after replacement.
• OE cross-reference: Coils and plugs call out OE references such as 305205RO013, 305205RO003, CM11121A and LKAR7BIX-11S to help ensure correct fitment.
• Complete kit: Shipping as a four-coil and four-plug set means a single service interval can replace all primary ignition components at once.
• Manufacturer support: BDFHYK positions itself as a direct parts maker with factory experience and aftermarket support for updates and buyer questions.

Who It's For

This kit is best for DIY owners and independent mechanics who need a full ignition refresh on compatible Honda Civic or Fit engines and prefer a matched set of coils and plugs for consistent performance. It suits vehicles showing classic ignition wear: shaking, slow acceleration, or increased fuel use after high mileage.

It is less suitable for owners who want OEM-branded parts from the vehicle manufacturer or those who require parts for other engine codes or later/earlier model years not listed in the fitment. Always cross-check the OE references in the images or part listing before purchase to confirm fitment.

Pros & Cons

Pros

• Good value for a full four-coil and four-plug replacement set that simplifies maintenance.
• Materials and construction claims (silicon steel, imported rubber, varnished wire) suggest longevity compared with generic coils.
• Iridium spark plugs offer improved starting and throttle response after replacement.
• Clear OE cross-references make it easier to verify compatibility with listed Honda models.

Cons

• Spark plug compatibility received mixed feedback from some customers, so double-check fit and heat range against the vehicle manual.
• The product description relies on supplier-sourced material claims rather than independent lab data.
