How does the ENA coil pack and control module match OE parts?

The ENA components reference common OE part numbers—including DR49 coil pack equivalents and LX381 ignition module identifiers—so the physical fit, mounting points and electrical terminals align with factory locations. The unit is a direct-replacement design intended for straightforward swapping without modification.

• Cross-references: DR49/DR-4910489421 and LX381/10482803 among other OEM numbers
• Coil pack: 3 terminals, bolt-on mount, 12V specification

• Included: 1 coil pack + 1 ignition control module, packaged together

What should I expect during installation and post-install checks?

Installation is a conventional bolt-on replacement in the engine bay; basic hand tools and standard safety precautions are required. After installation, check for secure electrical connections, clear any pending diagnostic codes, and verify smooth idle and consistent engine response under light acceleration.

• Mounting: use existing bolt locations—no drilling or adapters needed
• Electrical: match terminal counts (coil 3-terminal, module 4-terminal) and connector orientation
• Verification: scan for codes, inspect spark delivery, road-test at varied RPMs
• Warranty: 12-month coverage included with the package

Are there limits or reference numbers I should check before ordering?

Confirm compatibility by comparing your vehicle’s current part numbers or using an online fitment tool. ENA lists several OEM cross-references to help you validate fitment and avoid returns.
