Favorite Spark Plugs?

The manuals and archives are full of spark plug suggestions for my recently acquired all original 72Automatic. The car is used for daily modest driving.

The manual recommends a Bosch number that has been apparently superseded twice: W175T30 or W8DC or 7xxx. Some of you give the nod to NGK BP6Es or BP5Es or Even Denso W20EXU. For some reason no one seems to push Autolite or AC or Champion, yet I have used them in a Jaguar and countless other English and American Cars. I know the conventional wisdom is not to use the Platinum plugs, but what about the Iridium and Silver offerings?

Bottom line, with so many choices, what should I choose? Has someone taken a poll, what really is the best and why?

Thanks

I use NGK BP5ES (1 heat range hotter). I Put NGK's in evertyhing from dirt bikes,cars, chainsaws, lawnmowers etc. never had an issue.

Platinum and iridium plugs are used for their longevity, not for performance. In newer cars where access is limited, longer life is better. In an 02 changing plugs takes about 10 minutes, no real advantage.

This post was not intended to provoke an argument. If W8DC's were readily available in your area is that the plug you would choose? (The local VW speed shop near me still has em, but they also have the replacement "Yttrium" laced plugs.

My local red-front auto store also has Champion, Autolite, Delco and the odd SplatFire, but no one seems to endorse them as they do the NGK's. I have used all brands (except for the Splits) in the 25 or so boats, cars and snowmobiles I have owned and can't say I have any particular brand preference - except for the lowest price.

In the 02 crowd, there seems to be a very strong product loyalty (NGK) and I am just trying to find out if it is rooted in something tangible or is this just brilliant marketing and blind follow the leader?

Thanks

Over the past 20, 15, 10 yrs., etc. people on this board have tried all of the above brands you mention and they seem to keep coming back to Bosch or NGK. If you can still get the Bosch W8DC (make sure they are not WR8DCs, which are a resistor type plug that you do not need in your ' 02) then I'd go with them. As of a year ago they were $1.50 ea. from BMP in our area. The other plugs will probably work OK for you if you want.

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
