I need as much info on this as possible it will b my first time sprayin and would like to have the basics down******ive heard ngk v power 4554 and bkr7e plugs**............

 

You may want to retard timing a bit too, depending on what kind of tuning you had and if nitrous was in the equation.

Those plugs will work for a 50 shot..

 

its a conservative tune a/f ratio is good from idle to wot.... nitrous was not added to the street tune but will b after the install... n thanks jus wanna make sure im takin the right steps
