GOOD PRICE.

The read
What's actually worth knowing.
- These are surface discharge plugs that work best in high compression applications and typically require a special high energy ignition system, so you'll want to verify they're right for your specific engine before installing.
- They can be prone to fouling in cold conditions, which is a known tradeoff with this type of plug design.
- The 14mm thread with gasket seat and 12.7mm reach means you need to confirm fitment for your vehicle, as NGK makes many similar-looking plugs for different applications.
As of Jul 29, the NGK BU8H Spark Plugs Non Resistor 6431 (6 Pack) is a good price at $36.63 — versus a $33.25 typical price and a $28.69 12-month low, based on Amazon's own price history.
