Quick question on the specified spark plug for the 2003 GLX 4Mo 2.8L engine -code ATQ:
I just replaced the Factory "VW-Audi" marked NGK plugs in my car with dealer replacements ("VW-Audi" marked NGKs) and I noticed a difference between the NGK spark plug reference site specification (as well as other reference sites) and the plugs I pulled and replaced with new. This forum has also quoted the plug stock number that I am currently using - the BKR6EKUB
This is the NGK specification that was in the car when I purchased it at 37K - this is also what the dealer supplied when I purchased replacements a week ago. This is also the plug mentioned on this forum. I imagine this is the "correct" plug.
NGK BKR5EKUP - Stock 2890
This is the NGK specification according to the website
Sparkplugs.com and the NGK site quote this BKR5EKUP specification.
The heat rating of a "6" plug is, of course, cooler than a "5" plug.
Is the NGK site simply incorrect here?
Thanks in advance
