I use

NGK 2300 PFR5B-11 Double Platinum Spark Plug

The price at SparkPlugs.com seems high compared to the online dealers we recommend.

Whats the difference, there both NGK and platinum, but 1 is double platinum

[OwnerCS]

Double Platinum is the factory recommended.. Most long time owners on here use the NGK double platinum. I put some of the Iridiums on my Q when I first got it -- then soon afterward needed to reseal the valve covers (RTV), replace injectors, timing chain guides, hoses, knock sensors, and etc.

I figured since I was spending over $3,000 on parts to make everything under the plenum and around the engine like new, why let a few bucks on plugs stand in the way of having it be all original. So I went with the PFR5B-11. I found the online dealers (that are our sponsors) had the best deal over parts store prices.

I went to (pick your part) today and searched Q's, Maximas and J30's, and they had (NGK PFR5G-11) and
(NGK PFR6G-11), whats the difference and can I mismatch them...

5 is the hottest and 7 is the coldest heat range plug. Usually most times one would run a 6 for the heat range to be safe.
Here is a link to NGK.

I bought 4 (NGK PFR5G-11) and 4 (NGK PFR6G-11), they are all in great shape and only cost me just under $6. Can I install these together...

[Q451990]

You bought used spark plugs?

[1990_q]

Yes I did, and they are ALL in great condition...

I wouldn't mix and match heat ranges. I think IoS prices are about $60 for a set of 8 which is unbeatable.
