So I went ahead and got the NGK BRK7e spark plugs. Can I install them without getting a tune? My plans are to install these, a heat exchanger later this summer, then possibly a tune. Will my car be fine??? Will it run any different?

 

yes u can, get them in asap

 

good, do they make a difference in anything that you can notice?

 

your car will run smoother

 

You probably won't notice much of a difference unless your old plugs were old/faulty.

 

When should the plugs be changed?

 

how hard is it to change spark plugs?

 

Easy.

before u get ur tune

 

i have been searching everywhere for these damn plugs and noone seems to carry them. where did you guys get yours? i have tried O'Reilly's, Autozone, and Advanced auto parts

 

autolite 3922 are what i use. thats 2 steps colder

 

I always throw in a couple sets anytime I buy something from Summit. Freight is high if you just buy a set of plugs, but they always have something to blow the budget on...

Pretty much any more driving around town hunting parts is more expensive than waiting for the UPS truck to show up..

Generally have to order them from advance auto takes a couple days when they're not in stock. They carry the autolites and the ngks (7's and 8's) just give them the model number; but not the denso replacements.

Not sure what other brands people use, but if you aren't stock you shouldn't be using a stock replacement plug, it should be at least 1 step colder.

 

thanks

 

you know whats weird the advance auto parts computer pulled up autolites 3922 for a stock balt.
