So i wanted to ask you guys if anyone had the same feeling as me,I changed my KS like 2 or 3 days ago and i didn't torque wrench it, i just did it by hand, would tithing it to hard or too little make a difference on the mpg i get ? for some reason i think my car consumes more gas then before.

My other question is , whats the best way to seal the whole after Hid conversion in the fog light ?
thx guys

If your car is indeed consuming more gas than before, that's a result of retarded timing = KS retarding timing = overtightened so sensing too much knock. Grab a torque wrench and get it tightened correctly.

X2. Was it a factory KS or some cheap knock off?

Although... with improved timing maybe the driver feels like the engine is performing better thus driving more aggressive and decreasing MPG.

no the ks was oem

OEM parts can be defective, too. However, I doubt that is the case here.
