High Flow air filter

[05PTGT]

How much horsepower, if any, should a high-flow air filter give an 05 pt cruiser gt? Im talking simply about the high-flow filter, with no mods whatsoever to the rest of the intake.

I've read here that it's ~2-3 tops.

I put a Piranha in mine. Did it make a difference? Maybe a little - I did see a slight increase in mpg, and I like the sound. Looks kool under the hood too. The nice thing is that you can take it out, clean and recharge it, and put it back in - it'll outlast paper filters by many times over.

an intake is a supporting mod not a power mod. yes it will flow better, you see more of an increase when you add power mods.

if you want to make the stock system flow better remove the snorkle out of the airbox and that white resnator out of the top of the box and change the intake pipe to an aluminum one. the stock pipe crunches down to about 2" inside despite its 3" apparence.

Im not familiar with a piranha. does it go into the airbox or does it replace the airbox? And how does it sound?

2-3 hp isnt too bad, after factoring in what ill save buying filters, but what about mpg?

I doubt you will find much at all. We did a test on a dyno with back to back pulls. On a datyona T2 with stock air box. PAper, vs K&N vs no air filter in the box.

Uh as I recall there was about 3 hp difference, ie within the tolerance of the dyno.

I would be more concerned about the filtering so I would stick with the paper filter.

I have heard some people say that even though the numbers dont show much, that a high flow filter makes the car 'feel' more powerful and have a quicker response. Is that true?

[VNT]

Doubt you would notice anything, placebo effect.

Might go faster due to lighter wallet

What about the airbox mod...anyone checked any hp/torque numbers?
I removed the big unnecessary white piece in the lid, and can actually tell a noticeable difference, but i havent altered the bottom snorkel yet(big tube going from the fender to the bottom of the airbox). Would it be best if i waited until i get something to cut it with before i bother it, or would it be ok to go ahead and remove it and just drive without the snorkel until i can cut it?
Thanks for all your help.

It won't hurt to take that snorkel off but the air from the fender won't be directed right to the air box.

Oh, by the way, that "noticeable difference" you felt when you took the white piece out is called the "BUTT DYNO ACCELERATION FEELING". You get it anytime you add a free-er flowing air filter that makes a lot of noise.
