dude ..use what you want ... You asked what the best plug for the SR was not what the stock plug is ... In my experiences ( many many SR and Nissan Builds ) thats the plug that works best .... But do what you want to !! I really dont care !!

FYI .. The FSM is wrong because they Never used the non Platinum plug from the factory , thats what NGK's book said to use , and the NGK book was wrong ... The newest ( 2006 up ) NGK Books show the 11 gap as the non Platinum replacement to the OE platinum plug ...... I have been through this with the NGK Rep ..and he agreed the old Book was wrong showing the .8 gap ...

It's a matter of an Opinion.

For performance, BKR6E, BKR6E-11, Iridium BKR5IX-11, Bosch Platinum +2, all gave me similar HP's.

I have plenty of spark plugs now, I just need a dyno to try them all out

Courtesy Nissan says the BKR6E-11's are for GA16DE's.

Now my hood has a sticker that says Platinum plugs, DO NOT GAP. That looks like a stock sticker.

My wife's 2000 G20 has 44k miles on it, I pulled the plugs out to see that they were Platinums. Now this car doesn't look like got any service since it was driven off the lot

SOOOOO True,, no matter what you ask someone is going to have a different reason or proof and even facts against what you think or use... I myself is in search of "a plug" "best plug" to use in my De. because I'm getting ready to spray this motor and of course I need the right plug... and so far after hours of researching this big question I have in my head,, I'm going to use the BKR6E plug for now... right now I use the bosch platinum +4's and they are doing VERY GOOD, great performance and great gas mileage,, comeon guys are you really going to notice a 1-3 horse power difference in a motor... duh!, almost 18,000 on(500+weekly) them and they look better than the ones that came out of it with only 10,000 mi,,lol (NGK), I have'nt changed the brand of gas or oil I use through any of this and my car DON'T smoke,,, hesitate, burp, or fart on itself.... it just salutes and rides on out!!

I'm so glad Vadim chimmed in on this because I've read his post on plugs among others and I think I'm going to do what he says to do and untill I see otherwise thats my opinion... thats what this forum is for so we can compare Opinions and form our own...

I made this tread while I was at discount to get a quick response to buy them right there. Why are ppl still posting in it!? lol

I bet if you called them and asked them to look it up in the latest NGK Catalog , they would change that ..... Again , thats an old listing of the mistake in the old NGK Catalog ... World Pac also shows the BKR5E .... But again .. NGK is who built the plugs and they say BKR5E-11 ..

well, nissan who made the cars says its bkr6E. a .4mm gap difference will not cause any noticeable gains or detract from performance at all. Everyone buy what you think is right, for me, I will stick with my regular bkr6e for my all motor.

High boost or high CR will generally warrant a smaller gap if the OEM ignition is marginal in terms of current capacity.

No electrical circuit will generate more "power" than is just enough to get the job done.
A 100hp motor only makes 100hp and draws full running amps when the load is sufficient to warant it. So does the ignition circuit. It only EVER draws as much power as is needed.
If the plug is fouling, cold or hot, it's usually carbon tracking across the inner electrode via the ceramic insulator (carbon conducts electricity) to ground. In this instance the higher the spark energy the more the plug fouls up as the arc seeks the past of least resistance, ALWAYS.

High Voltage coil marketing is a ploy on ignorrance to sell the ultimate "Hot Coil".

The challenge is dwell time on the primary winding of the coil more so as average rpm has increased on the moder car. This is the only reason we have wasted spark and coil on plug systems, it's to gain dwell time by splitting up the duty cycle on more than one coil.
Old American V8 iron is where all this came from, V-Plug, Splitfire, Multi Spark etc, it's all because flame propagation in the heads is/was poor and all sorts of tricks were used to compensate for bad design. Just think of the real reason the Hemi was so impressive, it's combustion chamber was better and flame propagation was better.
Finally, if you run wasted spark, or know someone who does do the following;

Remove all the plugs from the head, keep them on the leads.
Ground only one plug so it can fire.
Crank the motor and look at how tiny and weak the spark is.
Ground the next plug fed by the same coil and try again.
Big, BLUE, spark on both plugs.
Reason: The Wasted Spark circuit requires that the circuit be terminated back to the coil. It must go through Gap#1 in the correct polarity, then Gap#2 in REVERSE polarity.

That being said, the point is, here are your 500, billion, 3 gazillion volts firing two plugs out of phase (one cylinder is always in polarity, the other is always in reverse).

But Mr Coil Seller is telling you you need 600 billion, 4 gazillion volts just to fire one plug.

The other thing is that the highest current draw is just prior to the gap being bridged, thereafter the air between the gap is ionized and therefore conducts electricity, so the required current drops until it gets to zero as the secondary coil winding voltage goes to zero.

Plug gap does not give more power and bigger bang and higher temperature.

The Nissan Catalog shows heat range 6 or 5 based on the climate and ambient air temperature.





additional edit: found this one courtesynissans site too. They list the bkr6e for the sr20de as well.

I will honestly say, the best MPG's that I have seen on my car with Bosch +2 plugs.

But I will have to say that Bosch Plugs only lasted for 20k miles for me. But for testing purposes, I did buy some more to track differences between new mods and other spark plugs.

Basically what it seems like an NGK plug can be made as efficient as a Bosch +2 Plug. It will need to be Side Gapped and Indexed though.

Pictures to show what I'm talking about.

NGK BKR6E plug and Bosch +2 plug



As you see the NGK plug has the ground electrode that will cover the flame from going down, thus making the spark not quiet as efficient.

Fixed, this is called side gapping


Indexing is pointing the ground electrode side to the exhaust valves, thus leaving it open towards the intake valves.

Interesting, I like how they are having the same gap, .44 for everything. When stock gap for conventional plugs is .031-.035

Plus this:
