Standard Ignition UF-409 ignition coil for the 1990-1992 Infiniti Q45 V8 4.5L sends the high-voltage pulse to a spark plug. This Standard Ignition coil is a coil-on-plug unit with one coil per cylinder.
- Advanced bobbin technology, a silicone magnetic steel core and optimized winding for accurate high-energy output
- Engineered and tested for spark energy output, impedance and durability in all operating conditions
- High-dielectric epoxy injected into the case and pulled into vacuum to remove air pockets and keep moisture out
- High-temp boot prevents high-voltage leaks
- Stainless-steel spring with internal ferrite noise suppressor prevents radiofrequency interference (RFI)
- 100% pure copper windings in the primary and secondary bobbins for resistance to internal shorts and dielectric breakdown
Quick facts
- Part: Standard Ignition UF-409 ignition coil
- Fits: 1990-1992 Infiniti Q45 V8 4.5L
- Condition: New
A weak coil can show up as a misfire, rough idle or hard starting. Before replacing one, look over the boot and connector with the engine off for cracks, burn marks or damage; if the coil is the cause, this one replaces it. This listing is one coil for one cylinder, and the fitment calls for two on the 1990-1992 Infiniti Q45 V8 4.5L.
Fits

Frequently Asked Questions
Does the Standard Ignition UF-409 fit the 1990-1992 Infiniti Q45 V8 4.5L?
Yes. Standard Ignition UF-409 is listed for the 1990-1992 Infiniti Q45 V8 4.5L, and the fitment calls for two per vehicle.
Does the UF-409 ignition coil come with a mounting bracket?
Yes, the coil comes with its mounting bracket. Mounting hardware is not included, so the fasteners are separate.
What connector does the Standard Ignition UF-409 coil use?
Standard Ignition UF-409 has one female connector with three male blade terminals, and it runs on 12 volts.
What can a misfire mean for a coil-on-plug coil like this one?
A misfire, rough idle or hard starting can come from a weak coil, but a worn plug or damaged wiring may produce them too. With the engine off, look for cracks or burn marks on the boot; a shop can test the coil.
Does this ignition coil have copper windings?
Yes. It has 100% pure copper windings in the primary and secondary bobbins, for resistance to internal shorts and dielectric breakdown.
