OTUAYAUTO Ignition Coil and Spark Plug Set UF507

The useful distinction here is that this is a paired ignition service set, not just a pack of coils: it includes four UF507 ignition coils and four AP5325 double-iridium spark plugs. That can suit a repair where both parts are due for replacement, rather than buying a single coil for a confirmed failure. The listing names several Toyota and Lexus applications, but fitment depends on the exact year and engine, so match those details before ordering.

Key specifications

The set contains four ignition coils and four spark plugs. The listed plug type is double iridium, and the coil reference is UF507, AP5325 is the spark-plug reference. The description also gives several replacement coil numbers, including 90919A2002, 9091902255, 9091902250, 9091902251, 90919A2004, and 90919A2007.

Listed applications include the 2010–2017 Toyota Camry with a 2.5L L4, the 2009–2018 RAV4 with a 2.5L L4, and the 2009–2019 Highlander with a 2.7L L4. The description also names Venza, Avalon, Sienna, Lexus ES300h and NX300h, and Scion tC applications. Its broader fitment text includes V8 vehicles as well, but says those vehicles need eight ignition coils. This package has four, so quantity matters if you are servicing a V8.

Who it’s for

It suits you if you have confirmed that your vehicle matches the listed application and want coils and plugs together for an ignition-system repair. For example, if a compatible four-cylinder vehicle has a diagnosed coil issue and the plugs are also due, replacing both as part of the same job may be more convenient than sourcing them separately. The listing associates worn ignition parts with symptoms such as misfires, hesitation, poor fuel economy, and warning lights, but those signs can have other causes, they do not confirm that this set is the fix.

It might not be a great match if you only need one replacement coil, want a package sized for a V8, or cannot verify the exact engine and part-number match. A single-part repair may be a better fit when testing points to just one failed component. The compatibility list is broad, and its year and engine details should be checked against your vehicle before you rely on a model name alone.

Included in the package

The package is listed as four ignition coil packs and four double-iridium spark plugs. No installation tools or other parts are specified. The description says the coils have silicone-rubber boots and claims the spark plugs are designed for a longer service life than common platinum plugs, treat those as maker-provided product claims rather than a guarantee of real-world performance. A one-year unlimited-mileage guarantee is also stated by the maker.

Practical doubts

Does a check-engine light mean these parts are the problem? Not by itself. The listing mentions warning lights among possible ignition-related symptoms, but diagnosis is needed to identify the cause.

What should I match before choosing? Check the vehicle year, engine size and configuration, plus the coil or plug reference where available. The product description lists UF507 and AP5325, along with several alternate coil numbers.

Is four coils enough for every vehicle in the fitment text? No. The description says V8 applications require eight coils, while this package includes four. Confirm the required quantity for your specific repair.

Buying verdict

This set makes the most sense when you need four coils and four plugs for a verified compatible application and prefer to handle both components in one repair. It is less suitable as a one-coil fix or for a V8 job that needs eight coils, since the package count does not cover that quantity. Verify the exact engine and reference numbers first, if they do not line up, buying a part matched to the vehicle’s confirmed needs is the safer route.
