NGK BPR6EY-11 4G37 1.8l gap size?

[FluxCapacitor]

I have attempted to use the "search" feature multiple times, so please guys don't give me grief. I am kinda newish to this forum, but, oh jeez, I have done some reading. haha

I've noticed people recommend the NGK plugs so I went with that. Are these the right plugs for the 1.8l? BPR6EY-11
They are V-POWER coppers. (I'm sure you guys know that. )
Also, is the gap already set? I suppose not, so what would the gap size be?

-------------------------------------------------------------------------------------------

Okay, I have a couple of questions regarding a car I am considering purchasing.
The car is a 1998 GSX with 100,000 miles on it.
What are the stock vacuum, boost, and oil pressure levels? I know those questions seem kinda dumb, but I'd rather ask a knowledgeable group of individuals.

Are there any things that I should pay extra close attention to?

If they allow me to, should I take the IC piping off and check for oil or anything in particular?

Any advice what so ever is 100% appreciated. I don't mind criticism as that is one of the only ways I will be able to learn a great deal about these cars. I am coming from a non-turbo background, so I will have to come a long way to gain the knowledge of some of you folks!

I do plan on picking up a Haynes manual before I go to look at the car. Should I carry anything else with me?

Thanks for having such a wonderful forum,
Nick

I would gap them to the factory recommended gap.

I know to gap them to factory specs. Everything under the hood is faded, so I couldn't tell for sure. Searching the web has got me too many reults:.044, .44, .90, on and on.

I have found it though, under a better condition hood. It is .039-.043. Thanks.
