Review About Denso Iridium ik20 spark plugs & SGO OIL
i installed ik20 plugs last year in june after reading reviews in different thread on pakwheels,
my main purpose for installing these was to increase fuel efficiency and to increase power.
And ALHAMDULILLAH both of these things were increased.
on oem plugs there was very limited power and poor fuel efficiency but after installing these fuel efficiency increased alot.
and i have noticed one thing that oil also plays very important role in fuel efficiency, when i was using shell hx5 semi synthetic oil car was not giving me more than 10 kmpl on highway unless i changed to SGO SUZUKI GENUINE OIL which is fully synthetic and now Ma sha ALLAH im enjoying a great fuel efficiency with increased power
so my advice to those who are complaining about less fuel efficiency and less power change plugs to ik20 and put sgo oil fully synthetic
