Here is the NGK partnumber key.

The following content by Jeff (SupraTurbo527) from the mkiv.com list.

Well, to begin with...stock plugs on the Supra are the BKR6EP-11 2978, which is defined as:

• (2978) stock plug - BKR6EP-11
• B = Thread Diameter of 14mm
• K = Construction type Hex Size 5/8" w/ ISO Projection Tip
• R = Resistor Type Plug
• 6 = Heat Range #6
• E = 19mm (3/4") thread reach
• P = Platinum-type plug
• -11 = x/10 - 1.1mm pre-gap (0.044")

Now keeping that in mind, (in what the car calls for, and specs it requires) now lets compare the BCPR7ES(-11) 1095/3330 and the BKR7E(-11) 1283/6097 plugs:

• (1095) BCPR7ES-11
• B = Thread Diameter of 14mm
• CP = Hex Size 5/8" w/ projected insulator (which is out-of-spec)
• R = Resistor, 7 = Heat Range #7
• ES = Standard 3/4" thread reach w/ 2.5mm diameter center electrode (which is prone to missfires)
• -11 = x/10 - 1.1mm pre-gap (0.044")
• 3330 is simply the BCPR7ES w/out the 1.1mm pregap (therefore gapped at 0.0315")
• (1283) BKR7E-11
• B = Thread Diameter of 14mm
• K = Construction type: Hex Size 5/8" w/ ISO Projection Tip
• R = Resistor Type Plug
• 7 = Heat Range #7
• E (Stand-alone Digit) = V-Grooved center electrode w/ 1.5mm diameter electrode.
• 6097 is also the BKR7E w/out the 1.1mm pregap (0.0315")

The 1283/6097 (BKR7E) plugs are pretty much the same specs as stock, but one heat range Colder, as well as non-platinum in a copper-core form. The center electrode, as compared to the 1095/3330 is also 1mm smaller in diameter as well as have a V-Groove. The smaller the diameter of the center electrode, the better the spark flow. (less chances of missfire) Think of the spark traveling through the center electrode as a water traveling through a small/steady stream, as opposed to some wide stream w/ wild rapids and uncontrollable tides. The V-Groove also furthermore helps the spark by directing the sparks toward the edges of the electrode, closer to the A/F mixture for the best ignition possible. If you ever have the chance, try laying down a OEM-spec plug...along side w/ the 1095/3330, and you'll notice the physical difference. Although they "may" work, it is not the correct plug for the car. The BKR-construction plugs are the way to go on the Supras (and not the BCP-construction plugs, which are designed more towards Hondas which require a longer insulator), and Brian Weaver at NGK Tech will also agree with me. The main reason people on this list use 1095's (and also 3330's) is that they are more readily available to the public. Many NAPA's, and even Pep Boys stock them and can also get ahold of them if necessary. The 1283 and 6097's on the otherhand, won't even show up on many stores' NGK parts list! The only means of obtaining these plugs would be through NGK directly, or by calling their main distributor (Monarch) at: 888-800-9629 (outside California) or 909-672-8501 (within California) or from their website.

of zoals mmarkk het ooit mooi bracht:

deze moet je hebben:

[Andre]

Yep BCPR7ES of BCPR7ES-11

[Andre]

Is het dan altijd ngk oid? Geen simpele bosch ofzo?

Niet zo eigenwijs doen als michello

gewoon NGK BCPR7ES

[mmarkk]

[MicHELLo]

Shut up, fools!

[KX250]

Kiek es wat ik tegen kwam... 1.5 setje graag

[Tjabbo]

iridium is kut

[KX250]

waarom? Ik dacht dat ze alleen belachelijk duur waren.

[Tjabbo]

werken slecht met turbocharged motoren

[emveha]

JeaH, Maar blijven op gas wel weer langer zitten. Voor de prijs kunje best een setje uitproberen.

[mmarkk]

Weet je het zeker, dit is Dealextreme uit China, is ws nagemaakt spul

[Tjabbo]

De mijne waren binnen 5000km kapot.
en fucking 12 euro per stuk!
