## Description

Sold in packs of 4.

Review: Checked all the gaps out of the boxes and all 8 were right on! - Well. I bought these to replace the ones in my Yamaha 350HP F350 5.3L V8 outboard motor. The original ones had a mere 115 hours on them but I was in the maintenance mode so, I decided to change the plugs. The runs as good with the new plugs as it did with the older ones so, not sure it was a major or miner improvement but, I had the satisfaction that the hourly service interval's been taken care of.
Review: Great for the price - different box than pictured. but same plugs
