 spark plug gap
sorry if someone else already asked this, but i just got new spark plugs for my car, and i need to know what to gap them at. also, when i ordered the spark plugs, they sent me NGK R plugs that are duel fire (2 small prongs instead of one) and i never had one, so i don't know how to gap these. i didnt just wanna gap it to what my old ones are (mostly because i dont think my old ones will be duel fire, and also, i dont know how to gap these.. )
can you help me out? i have the m44, 1.9L 318ti 1998 sport model.
also.. i ordered a intake boot from BMAautoparts, and they sent me the wrong one. the one i need is much smaller then anyone else's i saw on here. (and almost impossible to find) my car has a thing after the mass air flow sensor that controls how much air goes into the intake manifold. what is this used for? the ASC or something? hmm.. i was just wounderin.. haha |
