Default Aftermarket air filters...

Wondering about the benefits of these as opposed to buying a full blown air intake mod kit. The ones I were thinking about were the K&N filter or Spectre filter, but leaning toward the Spectre because its cheaper and I don't poop money out a lot.
Any little bit of increased gas mileage would help me out so if anyone has any input it would be much appreciated once again!

I wouldnt say so much a significant increase in fuel mileage...however I have noticed with my CAI kit I notied a definite increase in power and throttle response... so the fuel mileage increase may not be significant but the CAI kits make better use of the power so you could think of it like that....hope this helps.

I also like the removable air filter and the ability to remove for cleaning.... just remove....clean...dry and reinstall.......the washable filter is nice..

K&N are nice bit expensive. I believe those filters are removable and washable too.

Cool. I was just thinking 'cause I remember reading somewhere on the forums where someone just uninstalled the intake pipe that leads to the wheel well and put in a K&N drop-in filter and I think they said they gained a little bit more from that. That seemed like something feasible and that I can actually afford... Especially the Spectre filter. $20 for that compared to $50+ for the K&N filter or $200+ for a full blown kit. Also thinking that if I get a drop-in filter I can get a flex pipe and route it to the front grill like I've seen here in the DIY section sometime later.

I've done that mod. You need to reroute the air intake to the front of the engine bay to make it into a sorta like ram air. You can't just remove the stock intake tube. If you do that, you'll be sucking in hot air instead of the cold air we all want. If you're gonna do the spectre drop in filter, you might as well do the intake tubing at the same time. Like you said, look under the DIY section, you'll get lots of ideas.

Thanks Dan. So will the hot air going in instead of cooler air from the front cause any loss of HP or anything like that?

You want cold air. Cold air is denser than warm air. More air equals more power (computer will increase the fuel to match the increased air). Ever notice that your truck has more power on a cold day? Also, your engine will operate slightly cooler.

Just do the home brew CAI and a drop in K&N filter and be done with it for $55 bucks. Your going to get a better system and true cold air.

Sounds like a plan! I'll be checking out the CAI links in the DIY section again soon hopefully!

I did this last night...



Spectra Air Filter and parts from Lowe's plumbing... $40.00 I then pulled the cover from beside the radiator to get more cool air in, and still plan on a baffle or something to keep hot air away from the filter.
