Q1: Is this a genuine DENSO part?

A: This listing refers to a DENSO ignition coil. The 10R-03 5444 reference is the DENSO manufacturer number, and 90919-02258 is the Toyota OEM part number. DENSO is the original equipment supplier for these applications, so this part matches the quality and fit of the factory-installed coil .

Q2: How do I confirm if it fits my vehicle?

A: Check your vehicle’s existing ignition coil. If it is stamped with 90919-02258, 90919-02252, or 10R-03 5444, this replacement will fit. Also confirm your engine is in the 1ZR/2ZR/3ZR/5ZR family and matches one of the models listed above. The coil uses a 4-pin connector and is typically required in sets of 4 .

Q3: What are the symptoms of a failing ignition coil?

A: Common signs include engine misfire, rough idle, loss of power, poor fuel economy, and a flashing or steady check engine light. A diagnostic scan tool can identify which cylinder is misfiring. Since coils are often replaced as a set when one fails, it is recommended to inspect all coils during service.
