the car is a 2001 max. this is the second time happen, this morning when i tried to start my car it didn't cranked it 3 times and waited like 5mins and then started it and work well, so the battery can't be the reason, and i replaced the starter last summer and it is working. Then i went to school and after class (1hr later ) the car started fine one crank. the only thing i can think of now is it can be eaither the spark plugs or the new battery terminal i installed buut i installd it like a month ago and this started two days ago. What do you think can it be the spark plugs?

here are the pics of the terminal any thing wrong with it?



also is it ok to put Bosch plugs on this car coz a lot of ppl say that bosch are for german cars b/c NGK are double the price of bosch

thanks
