so i was doing a bit of research and reading here, and looks like Densos are notorious for unscrewing themselves and blowing blocks and other not so nice things to the engine. those are the ones that are in my car now, and id like to get them outta there ASAP

would the BKR7 be a better solution to my mods?
15% pulley and Alta intake/exhaust.

also, what should they be gapped at?

im sorry for another start to this Q, but i read way too much and id just like to get a few answers for my specific car.

any other ones possibly?

 

The BKR7EQUP is the JCW oem plug and a very good one. No need to gap it as it is a 4 prong plug.

Been running them for years with no issues. And they are fairly cheap too.

 

good to know, thanks

 

Get a BKR7E plug. It's copper and about $1-2 a plug. Gap at .032. It's not multi point so it's more consistent. And it's copper which is a better conductor than platinum. The only down side is it should be replaced around 10k miles. But i domt mind that. I've ran the same plug on my Audi s4 (twin turbo at 17 psi) for years with no problems.

 

Here's a chart that decodes the plugs.

They might have the bkr7es which is fine too. If they have the -11 then it will need to be gapped down to .032. The bkr7e and the bkr7es are both .032 from the factory but I always check.... Hope this helps!

 

is that the Desno Irridium is really great but the tiny electrode errodes in the SCed engine so it changes over time. That's why I stopped using them. Many different plugs have blown out of heads. I think that the Densos get blamed for popping out of heads because they were the rage in plugs for so long on the R53 and so many were running them. Stock plugs have popped too. Make sure you torqe the plugs properly, and check the torque periodically. The steel of the plug body and the Al of the head have different thermal expansion co-efficients, and this can alway lead to issues.
