under the hood (when it was still black) - Toyota Carina, 1.5 L, 1990

My advice to you, throw this zero-up, it will bring you a threshing floor in the engine in the summertime, it will not bring anything good anymore = (

yeah, easier, and swallows dust, too, unfortunately

well why? the engine really breathes easier with it

oh well, with proper impregnation with a special agent,
he will not catch anything, everything remains on a viscous special fluid,
you just need to properly take care of it,
and you can pour additives for the injector and that's all

And you can just rent it will be cheaper.
