It is general question concerning DENSO SPARK PLUG that is often.
 |
What is the optimum heat range for a tuned up Golf4 GTI 1.8L Turbo?
(Tuning: Turbine Changed, High Volume Injector Installed, and ROM Adjusted to give an output of 200PS from 150PS.) |
|
| It's difficult to give a heat range based on going from 150PS to 200PS alone, and it's best if you judge the condition of your current plugs and judge for yourself, but as a general rule, for boost pressures between 1.0 and 1.2kg/cm2, an IK24 should be sufficient. During the winter, #22 should improve starting and low speed feel. The heat range is different depending on how the engine has been tuned and how it's used; using an increase in heat range of 1 or 2 as a starting point, decide on a heat range, always looking at the condition of your current plugs. |
