[s-cars] Spark Plugs

[William Noland]

Haven't posted to the list in a long while, but feel the need to chime 
in on this discussion. I agree completely -- spend the extra bucks and 
go with OEM plugs. We had this very discussion a few years ago on the list.

The UrS's pushed the envelope quite a bit with relatively high (esp. for 
the early 90's) compression ratios and boost levels. (Chipped/RS2'd cars 
push it even further.) Throw in sustained high speed running (can you 
say Autobahn?) and one can understand why special, expensive plugs were 
spec'd for these cars. The compression and boost figures are still 
impressive, even compared to more modern cars. Just no comparison to 
your daddy's Oldsmobile.

Problems with "cheap" plugs tended to show up on track days, or after 
sustained high speed interstate flogs. Suddenly, car no run so good 
anymore. So, ya pays your money and takes your chances. Though my UrS is 
in the hands of my step daughter these days, I'd write her out of the 
will, if she used anything other than OEM plugs. If you want to save a 
buck, buy windshield washer fluid in 50 gal. drums. Do not skimp on plugs.

OK...back to lurk mode and S4 V8'n.........
