I just had the sparkplugs replaced on my 2006 Tacoma 2.7 4 cyl. automatic. The recommended plugs are the ILFR6C11, but the mechanic used LFR6A1X-11 plugs instead (both are iridium). The engine definitely runs smoother now, but I would like to know what the difference is between the two plugs. Thanks.
