I tried looking in past posts but none made it clear to me what exactly the part # for the ngk spark plugs are for a 96 g20t. I also tried in my owners manual and found nothing of use. Also if I am going to be doing the spark plugs should I go ahead and get a set of NGK wires also?
Thanks.

Ok I am an idiot I just found their website and got the info I needed. It also has on there an oxygen sensor? Should I get one of those? What exactly is it for?
Thanks.

Just to make sure it said the # for the plugs was PFR5G-11? and for the wires was NX11?
Nope!

You want the PFR6B-11's if still available or the PFR6G-11's which replaced the prior. If I'm not mistaken, the 5's are the incorrect heat range for the '91-'96 SR20's. I believe the 5's are used on the most recent model SR20's.

Plug wires are correct though.

If you still have your owners manual, look at page 9-18 Technical and Consumer Information. It lists th standard plug as PFR6B-11 (Platinum) and the optional plug as BKR6E (Copper). the plats runs for 60,000 and th copper need replaced at 30,000.

I would opt for the manufacturer recommended plug of PFR6B-11 and not the hotter '5' range plug.

I hate to say it, but I do believe the NGK site to be incorrect.

On a side note, back in I believe it was '93 Nissan released a TSB for SR20DE powered vehicles that stated to switch the stock standard PFR5B-11 plug for the PFR6B-11 due to loss of performance, driveability issues, and poor gas mileage. Nissan found it was the incorrect plug to be using.

Hey nismo the ngk website said thats what they take... www.ngksparkplugs.com . Are you for sure that I want the 6G?
Also, I just went to the site and it listed the PFR5B-11's. 'B' not 'G'. I chose Cars - Infiniti - 1996 - G20 and that came up.

Hey I just looked in the manual where you said and I do see it but it says for Hot PFR5B-11, Standard PFR6B-11, and Cold PFR7B-11. So.. I am sorta confused, it doesn't state what hot and what cold is etc... I guess it is always safe to stick with the middle one. =)

Oh and I just found a site that states that when modding an engine it is better to switch to a "cooler" plug to avoid severe damage when driving it hard. I am pretty confused now.

Personal opinion here:

Just go buy a set of PFR6B-11's and be done with it. Or do like I did and buy a set of BKR6E's for a lot less an be done with it.

If you do buy the BKR6E's do not buy the BKR6E-11's. They are for the 1.6 GA16DE, not the SR20DE.
