Got the plugs sooner than expected and they were the perfect plug for my 90 HP boat engine.

These parts work fine. We bought extra items so that our order would qualify for same day arrival because we needed them quickly. They ended up a day late which was a little aggravating but glad we got the parts.

Bought for my Mercury Outboard motor on my boat. The price is excellent and made it easier to get than running to a boat shop,
