I currently have a plain white air filter (fairly new) and was wondering if a K&N would make a noticable difference in mileage

edit- Im looking for easy to install bolt ons that give better mileage and possibly a slight increase in power

It's highly unlikely you'll see a difference in MPG or power. To better your MPG, your best bet is to use cruise control more often.

no you probobly wont feel any difference or notice change in MPG, on the other hand an aftermarket air lid would give you better MPG and power by allowing the engine to breathe better

i was considering the SLP air lid, it should fit right over the stock lid thingy correct?

would

be better than a SLP air lid? also would the SLP lid fit on 98 3.8l

When I bought my SLP I also bought a new filter, k&n one, because I needed it.

I don't really notice a difference.

I would skip the K&N filter.

As for the lid, if you're looking for a V6 lid, I know Whisper makes them for the 3.8L.

Thanks, ill most likely be getting this after i get a job this summer
So far my list of mods i plan to get are

Flowmasters (slight power increase, but i like the sound)

Let me know how your six sounds with the flowmaster catback.
I'm curious to know.

save your cash and get a V8 why mod so much just to get where the other is stock

and the flowmaster will decrease your power, 80 series flowmasters are very constricting. get a cutout or go tru duals

K&N is good but they say HOLLEY is better
