Direct Injection carbon intake valve cleaning

[hardwang]

i have never had it done on our car.
we just do the italian tune-up. it's also more delicious.

I also do that once in a while. Extremely fun.

But I'm thinking.. maybe its not enough. Wala pa akong alam na shop na nagtatanggal ng carbon deposits dito sa Pinas. And the carbon deposit issue on intake valves of DI engines is real and inevitable...
