Frequently Asked Questions About Nissan Frontier Spark Plug Change Without Removing Intake Manifold

Q: What Makes the Frontier Spark Plugs Hard to Reach?

A: On the 3.3L and 4.0L V6 engines in many Frontiers, Nissan designed the intake manifold to sit very low and tight up against the cylinder heads. This covers the spark plugs by leaving only about 2 inches of space to work in.

Q: Is it possible for a Non-Mechanic to do this repair?

A: While challenging, it’s possible for a moderately skilled DIYer to perform this process with patience and the right tools. Having small hands is also an asset. Proper preparation and caution when working deep in the engine area is essential.
