We updated Spark Plugs a while back — moving all Iridium to the top -then Platinum ( all makes ) …and lastly ..older style copper plugs… this really worked well ..especially after we talked with Raleigh marketing manager for lines and got problem areas like Hi-Pop sublines ( PN Codes ) eliminated that contained ALL TYPES of plugs ..that was the biggest problem for cleaning up e-cat.
Now we are looking at Friction ..and trying to figure out how to ELIMINATE excessive supercessions on the older style ( BCD to BXD etc )
Here is what we are testing — would it work for your store ? It either will be great or we ail crash & burn ..keep your fingers crossed
