RANSOTO Ignition Coil & Double Iridium Spark Plug Kit for Nissan Altima Rogue Sentra Versa NV200 — Set of 4 UF549 & 9029, OEM Fit,

RANSOTO's kit pairs four UF549 ignition coils with four double-iridium 9029 spark plugs to restore reliable ignition for compatible 2007–2019 Nissan 1.6L–2.5L engines.

This replacement kit is engineered to match OEM fit and function for many Nissan models, offering high-conductivity coil windings and iridium-tipped plugs designed for long service life. Whether you're addressing misfires, hard starts, or degraded fuel economy, the components in this set are built to deliver stable spark delivery and improved combustion consistency. Before installation, confirm vehicle compatibility using your VIN or the model/year list to ensure correct fit.

How will these coils and plugs affect starting and idle quality?

Swapping worn coils and fouled plugs with this RANSOTO set typically reduces misfires and shortens crank time by restoring consistent spark intensity. A steady ignition source helps the engine achieve smoother idle and quicker starts across operating temperatures.

• 4 UF549 coils engineered to replicate factory electrical output and geometry
• 4 double-iridium 9029 plugs for stronger, longer-lasting spark electrodes
• Improved combustion consistency reduces hesitation and rough idle
• Designed to resist fouling and thermal degradation for extended service intervals

Which vehicles and part numbers does this kit replace?

This set fits a range of Nissan models from 2007–2019 with 1.6L, 1.8L, 2.0L, and 2.5L inline-4 engines—check your vehicle before ordering. It replaces numerous OEM and aftermarket references, making it a direct swap for many common part numbers.

• Compatible models: Nissan Altima, Rogue, Sentra, Versa, Cube, NV200 (2007–2019 where specified)
• Ignition coil part cross-references: UF-549, C1696, COP292, UF549X, GN10241, IC629, 22448ED000, 22448JA00A/C
• Spark plug cross-references: 9029, 22401JA01B, 22401JA07B, 90919-01281, DILKAR6A11
• Confirm fitment via VIN or vehicle compatibility tool before installation

What materials and design features improve durability and performance?

RANSOTO coils use copper-core windings and dielectric epoxy to maintain strong, reliable electrical transmission, while the spark plugs use an iridium-tipped electrode and alumina ceramic insulator to withstand heat and reduce electrode wear. These choices extend operational life under typical driving conditions.

• Copper core windings for high conductivity and stable spark energy
• Dielectric epoxy potting to protect coil internals from moisture and vibration
• Iridium center electrode for a fine, long-lasting spark tip
• Alumina ceramic insulation to resist thermal stresses and fouling

How do I know when to replace the ignition coils and spark plugs?

Consider replacement if you notice rough idle, longer starting cranks, reduced fuel economy, or check-engine codes related to cylinder misfires. Proactive replacement at recommended intervals can prevent catalytic converter damage and maintain drivability.

• Signs: hard starts, uneven idle, reduced power, engine codes (misfire)
• Maintenance tip: replace coils and plugs in matched sets for balanced performance
• Always inspect ignition boots and wiring for damage during service
• Use OEM torque specs and anti-seize only where manufacturer advises

Who is this for? This RANSOTO coil and spark plug kit is aimed at DIY mechanics, independent shops, and fleet maintainers who need a cost-effective, OEM-compatible ignition replacement for Nissan 1.6L–2.5L engines from 2007 through 2019. It suits drivers troubleshooting misfires or ignition-related drivability issues and anyone replacing worn ignition components to restore responsiveness and fuel efficiency. Always verify fitment for your exact model and year before purchase and follow safe installation practices or consult a professional mechanic if unsure.
