d16Y7- Spark Plugs

[Blazing angel]

hello all, here is my situation. I was just about to seafoam my car, but realized i need to change my spark plugs. I've never done this before, but it doesn't look too challenging. I lost my owners manual, and my google skills have failed me. What size wrench would i need, as well as would i need to gap the spark plugs? Also, are ngk spark plugs decent for my stock engine? a D16Y7

NGK spark plugs are great, i love them myself. as fare as the spark plug socket you will need off the top of my head i would have to say 5/8? there are usually two typical sized spark plug sockets its the smaller that youll need. fyi, spark plug sockets are the ones with the rubber ring on the inside so the plug stays in the socket. and yes i would recommend checking/gapping the plugs. under the hood there is a white sticker with info about the engine there should be a gap size. or you can call autozone or wherever you bought the plugs and they can tell you the gap for your car,

also remove one wire and plug at a time so you dont mix up the wires. and dont over tighten the plugs.

Seafoam will foul your spark plugs, so Seafoam first, then replace the plugs.
