Just bought a 1998 Black Maxima SE 5-speed!!! Awesome car. So much pick up. I love it. I'm gonna get a Tune-up done on it. Since the shop is gonna replace the air filter, should I buy a K&N for them to install? Someone I knew once told me that this would increase HP a little. Is that true? Are there any benefits of installing a better air filter, (besides getting intake later on)? THANKS!

 

Wait if your talkin about the airfilter inside the stock air box i dont really think so, i dont tink you will be able to feel it, but it helps a lil

 

you car breathes better, getting more air into the engine. it wont be any noticeable hp that you can feel tho. anyways congrats on your purchase and enjoy.

 

if you replace the flat K&N panel filter with K&N cone filter then yes u will pick up 2-3WHP.
