Re: [alfa] Too Hot, or....

Hi Robert:

If you've ever seen an owners manual from any of the earlier 105/115 
Alfa's, there's usually a mention of two applicable plugs from Lodge (the 
OEM supplier).  The HL was recommended for the more "leisurely" (my words, 
not Alfa's) driver, while the colder 2HL was recommended for the "sport" 
driver keeping the rpm's high for extended intervals.  The moral of the 
story is to use what fits your needs best.  Assuming correct ignition 
timing, carb tuning, etc., keep an eye on the color of your plugs.  Black 
might indicate too cold, white too hot, but a dry, even, medium tan color 
is about ideal.

I always used the cooler 2HL Golden Lodge's in my 1750 GTV (many years 
ago), and still like the cooler BP7ES NGK in my '74 Spica Spider.  The 
NGK's also seem to have a wider tolerance to variable driving conditions 
than some other brands.  I can sit in traffic for a while, then hit an open 
road, and all is well.  After trying a lot of different plugs, I won't 
bother with anything other than the NGK's in my '74, but prefer the 
single-electrode Bosch Platinum's in my '87 Bosch Spider.  Don't be afraid 
to experiment, but I'll bet the NGK's will be fine, in either heat range.

Regards,
