What It Helps Address

• Misfires caused by worn or heat-damaged coil boots
• Ignition breakdown from cracked or hardened silicone boots
• Moisture intrusion at the spark plug well
• Weak spark transfer between the coil and spark plug
• Service issues on high-mileage Lexus and Toyota ignition systems

Installation Notes

Verify the coil boot length, terminal style, and engine application before installation. Inspect the ignition coil, spark plug, and plug well for carbon tracking, oil contamination, or heat damage, and correct those conditions during service. This part cross-references Beck/Arnley 175-1068 and NAPA Mileage Plus 6718184 for the same application.
