In this review the tester focused on whether the UF-417 ignition coil pack set of 4 is a practical replacement for Acura TSX and RDX owners. The bottom line: this set is aimed at drivers who need a direct-fit, OE-level replacement to resolve misfires, poor economy or rough idle. The reviewer found the coils to be straightforward to install, made from durable PBT and PPO materials, and effective at restoring stable high-voltage output when fitted to compatible 2.3L and 2.4L engines. It is recommended for anyone who values fit, value and reliable performance.

Key Features

• Vehicle Compatibility: Designed specifically for 2004-2008 Acura TSX 2.4L L4 and 2007-2012 Acura RDX 2.3L L4 applications, making fitment checks simpler for those models.
• OE Standard Performance: Manufactured to OE level durability by a TS16949 certified maker, offering consistent high-voltage output under normal driving conditions.
• High Grade Materials: Constructed from Germany imported PBT and U.S. domestic PPO to improve heat resistance, abrasion resistance and corrosion resistance for longer service life.
• Engine Performance Relief: Replacing worn coils reduces common issues such as ignition misfire, long crank time, hesitation and poor fuel economy when the rest of the ignition system is healthy.
• Compatible Part Numbers: Matches OEM-replaceable references such as UF-417, 52-1781 and 30520-PNC-004 to aid identification and ordering.

Who It's For

The set is best for DIY mechanics and independent shops working on mid-2000s Acura TSX 2.4L naturally aspirated engines and 2007-2012 RDX 2.3L turbo engines who need an OE-level, 100% new replacement for failing coil packs. It suits owners experiencing misfires, reduced power or rough idle who have confirmed part number compatibility.

It is not intended for vehicles outside the listed years and engine types, and buyers unsure about OE numbers or cross-compatibility should consult a parts diagram or dealer before purchase rather than assume fitment.
