Frequently Asked Questions
Why should spark plugs and ignition wires be replaced together?
Because both components wear over time, replacing them together restores the complete ignition system and helps reduce future misfires and drivability issues.
Do iridium spark plugs improve performance?
Iridium spark plugs provide a more consistent spark and longer service life than conventional plugs. While they won’t dramatically increase horsepower, they help maintain efficient combustion and reliable engine operation.
Can bad ignition wires cause poor fuel economy?
Yes. Weak spark caused by deteriorated ignition wires can reduce combustion efficiency, leading to lower fuel economy and rough engine performance.
Is this a direct-fit replacement?
Yes. The AUTOREBO kit is designed as a direct replacement for compatible Nissan and Infiniti 3.3L V6 applications using factory-style wire routing and ignition components.
