Wondering if the 4 prong spark plugs will make any noticeable difference, it says on the box something like:
if you do not feel a difference Bosch will pay for the plugs.
Is it worth the extra $5?

For the price they may not be worth it but i feel a noticable diffeence with just an exhaust and a K&N. For some reason i like them but have heard good and bad, and they dont do anything for the jetta so im not sure guess it depends on the car. They all have a diff. attitudes.
