Courtesy sent me the wrong plugs for my car, at least I think so.
The plugs that came out were NGK BKR6ES-11 and I got NGK BKR5ES-11.
Can I use them? or should I send them back?

VG -or- VE???

Go to ngk homepage and open that code. If I remember right, the temp (R5) range is different: you have to know what u do with u engine, how hot its gonna run.

R5: This works fine on VG30E: NGK PFR5C-11 2271 Laser Platinum

I have a VG30E also. So you are telling me that the platinum plugs will work for meIf I don't go with the ones that came out. What advantage is it to the platinum plugs?

By the way, I love your website....

WiKing,

I went to the home page and did the search on my car. The laser platinum plug for my VG30E was NKG PFR6B-11 4014 Laser Platinum instead of NGK PFR5C-11 2271 Laser Platinum. Interesting....that we have two different part and stock numbers for the same engine. Your thoughts? Could it be the year? Mine is a 91 SOHC.

You'll be fine using that spark plug; no need to return! The 5 just refers to the heat range of the spark plugs (the lower the number being a hotter plug), and the VG engines apparently were fitted with BKR5ES-11 at the factory. Most people will find BKR6ES-11 because that's sort of the standard in-between plug where most auto parts store will list as a fit too. I myself, when I changed my spark plugs on my VG for the first time, pulled out BKR5ES-11. You'll be fine using them.

Platinums are only good for long service life. Otherwise, go with the BKR5/6ES-11s. The VG doesn't need anything pricey and special, and the v-groove copper core is a good enough design. Also, using coppers and changing them every 2 years or 30K ensures that you get a fresh set of plugs at least every 2 years, and avoids any chance of thread seizure due to leaving the plug in an engine too long. When you replace, just lube the ceramic portion of your spark plugs as well as the inside of the spark plug wire boots with Permatex dielectric grease.

According to the Haynes manual, the OEM plugs are NGK BKR5ES-11, which is what you have now. Gap is 0.039 to 0.043 inch (1.0 to 1.1 mm).

Use first what u've got. Btw, different catalogs give different numbers; (why?). Open the ngk codes, use ngk home page.

I am instant expert in this platinum issue: have just one yr exprience with platinum; anyways works as well as std NGK. (ngk customer service is a blk hole, btw).

Standard plugs are rec to be changed every 10k miles, thats why I bought platinum (60k is promised). If works as promised, platinum will come out ½ cheaper, 6x LESS work.

Std plugs really start idle sputter at 10k. Even 5k used plug pressure tests show wear and reduced spark. The mentioned soot buildup is possible, not a problem I suppose. Never used any contact grease on that hot part... I am suspicious of such practice, possibly will flow off and cause spark miss. High voltage will jump to shortest ground without any special attention, no bad connections 'possible'. Dirt is its 'friend'.

Btw. Ignition is the culmination point how much u get power, how much of the saudi gold is wasted. If one wants more miles per dollar, one invests in that POINT.

Ok,

I installed plugs, gapped as per manual to .044. After I finished the car's idle was off, drove it around the block, ran like crap. That night I left the battery's neg terminal off, thinking that that the ECU needs to reset itself. The next day I drove the car and while I was running it, it went back to its norm, boy was I happy. I do have a question though, Is it a common practice to adjust the timing when new plugs are installed?

No, you don't need to touch the timing. However, the spark plug gap for the VG30E motor is in a generous range of 0.039" to 0.043". Don't listen to the NGK website, check your owner's manual instead. It may have ran like crap because the gap is too big. I usually set mine to 0.041" to bridge the gap. But if your car is running good, don't worry about it.
