Hi all,

I just installed new denso idirium IW16 for my satria.

And yesterday i did injector cleaning + fuel system cleaning ( t-body, manifold carbon ) at tyrezone .

after finish all, the guy drive my car n he say choke a bit , but its ok. then he take out one of the spark plug n see .... the bottom leg like so black like burned.
then i heard ppl say better dun use good plug during cleaning carbon process ..

after he just put back the plug ....

Actualyl i go to tyrezone to clean injetor. Then the guy recomend me one package to clean trottle body and intake manifold.... so i take lor.

They pour into somethin like a can, and it spray directly into my intake manifold ...

Just that im worry see-ing my denso leg so dark >< its a new set somemore ....
