How much extra HP can I expect to get in my 2004 SE 3.5l by adding an air
intake system and a Cat-back dual high performance exhaust? I heard 50. Is
this true?

Usually normally aspirated performance enhancements (intake, exhaust,
UDP etc) tend to increase a car's HP by 15%. So your Maxima's HP will
probably increase from 265 HP to 265 * 1.15 = 304.75 HP, a 39 HP increase.

Of course the noise will increase, too. Be prepared to live with it.

IMHO that's on the high end of what you get from cars that already have
"high performance" engines like these do. I'd be shocked if you ended up
with even 10% HP increase from these mods and sometimes these types of mods
LOSE power, they just make more noise! Even 40HP from an air intake and
exhaust isn't going to happen on one of these cars.

Not to mention the risk of voiding your warrantee, and not being able
to pass local emmision tests.

You wouldn't look like such a dumbass if you paid better attention to
what was said. There was never any dispute about the use of oiled
filters. It was your statement that everyone was as incompetent as you
and therefore would not be able to clean a throttle body that got you
laughed at. Your problem appears that you don't have enough common
sense to figure out what 'needs' a dealer's expertise and what doesn't.
In YOUR case. you should take it to the dealer for everything. Perhaps
when you grow up, it will come to you.

BTW, if you think being told before that you were a goof was a 'flame',
you truly don't have a clue and it is more obvious why you are laughed
at.
