Standard Ignition SPP239E Direct Ignition Coil Boot - Front

Direct Ignition Coil Boot for Nissan Applications

Standard Ignition SPP239E is a direct ignition coil boot built for OE-style replacement on select Nissan front applications. It uses a straight boot configuration with a phenolic tube and silicone tip, plus an integrated spring and 2k ohm resistor for proper coil-to-plug connection.

Compatible with Nissan TITAN, Nissan TITAN XD, Nissan NV2500, and Nissan NV3500 front positions, this ignition coil boot supports clean spark transfer in vehicles that rely on a direct ignition setup. The Standard Ignition SPP239E is a practical replacement when the original boot shows wear, heat damage, or electrical resistance issues.

Detailed Description

Standard Ignition SPP239E is engineered as a direct ignition coil boot for front-mounted applications on 2016-2023 Nissan TITAN XD, 2017-2023 Nissan TITAN, 2017-2021 Nissan NV2500, and 2017-2021 Nissan NV3500. This part number is an OE replacement solution for restoring the connection between the ignition coil and spark plug while maintaining the correct boot length and resistance characteristics. The phenolic tube and silicone tip construction supports heat resistance and electrical isolation in demanding ignition environments.

This part cross-references Standard Ignition SPP239E and is also associated with SPB302 for the same application.

What It Is Used For

• Replacing a cracked, hardened, or heat-damaged ignition coil boot
• Restoring spark transfer in a direct ignition system
• Addressing misfire conditions caused by worn boot insulation
• Correcting resistance-related ignition performance issues
• Servicing front ignition positions on Nissan TITAN and Nissan TITAN XD models

Installation Notes and Tips

Verify the vehicle year, model, and front position before installation. Inspect the ignition coil, spring contact, and spark plug well for carbon tracking, corrosion, or oil contamination before installing the new boot. Confirm the boot seats fully on the coil and spark plug to maintain a secure electrical connection. For Nissan TITAN, Nissan TITAN XD, Nissan NV2500, and Nissan NV3500 applications, compare the removed part to SPP239E to confirm length and configuration.

Quality Assurance

Standard Ignition supplies OE-style ignition service parts for direct replacement applications. SPP239E is built to match the specified boot configuration, material design, and resistance requirements for the listed Nissan front applications.
