autolite 103 or 104's? o2 brand? My engine is running 11-1 compression and right now i have the stock heat range plugs in it and it is running ok, but i think it could run a little better. Golen recommends 103's but that seems a little too cold to me? What are you guys running with 11-1 compression? Do you think I should try 104's or go ahead and use 103's.
Also I changed my o2's with the bosch brand sensors, and again the car is running ok but then i read i should only use the stock brand ac delco o2 sensors. I got the bosch's cause they were cheapest. The NGK's were twice as much and so are the ac delcos. Should I try the ac delcos?
