Comments about NGK Laser Iridium Spark Plug (IFR5E11):
These are the best plugs not only for subarus, but for asian cars and other car brands. Replaced OEM NGK platinum in my subaru at 150k which still looked good. Am now pushing 300k total with these NGK iridium and still going strong. Am even getting 30-32mpg highway, which is outstanding in a subaru. Also have NGK iridium in a dodge and volvo and have never had a problem with them unlike Bosch or autolite plugs.

Comments about NGK Laser Iridium Spark Plug (IFR5E11):
My 4 cyl. idles smoother and engine certainly is more responsive- especially, with highway driving.I noticed an immediate improvement after installing them.Cant comment on gas mileage yet.I tried the Denso IK16 which are very good but these are even better.Never thought spark plugs could make that much of a difference but the Laser Iridiums has for me !

Comments about NGK Laser Iridium Spark Plug (IFR5E11):
Direct replacment for my 2000 Infiniti Q45 at 108,000 miles there was an immediate and noticeable change in throttle response and overall power. Car also started faster temp was about 51 degrees. Not sure about fuel mileage yet but if I stay out of the throttle i'm betting it will be better too. Price is great too considering you only have to change them every 100,000 miles.
