So I pulled out the NGK 96987 SILZKBR8E8S this past weekend. Mostly because I had to remove the Delphi coil packs I was running since they were causing a BSD issue, so I thought what the hell, let me install the NGK 97506 SILZKBR8D8S I had ordered (thanks @Bnks334 for the info).
The 97506s are running good. I gapped them to .025" and have grabbed numerous logs on stock flash, ACN91 fuel. Minimal to zero timing corrections for the most part, which for ACN91 is really good. I am going to throw back my E50 tune and see how they perform with more boost. I will report back once I grab some data.
In the meantime, can you guys please take a look at the 96987s I pulled out and shed some light on how they look/how my engine is running? They have about 6k miles one them. Gapped at .022”. one half mile race
event.
