Fuel filter, spark plugs, higher octane gas. Is this stuff really gonna make the car quicker?

 

Can't hurt. But if you're looking to drop a second or two or something like that ... forget it.

 

well, i woodnt say faster, a better word for it is "cleaner"........using higher octane gas, a new fuel filter and new spark plugs.........these are not exactly considered performance products........for a maxima u really shouldnt use anything less than 91 to start with.......new spark plugs and a new filter will just keep the car running the way its supposed to

 

i duno i use to run 17's, after puttin in my ngks, i break 9's every time, sparkplug is the biggest mod u can do to a maxima man, get on it!

 

 

You must have had a nasty hole in your fuel map! BUAHAHAAAA!
