Don't forget that this will be different for every vehicle and this is for my specific car but I would expect the pattern to be the same for all cars just a different gain. Plus it is less than 1 hp.

Short ram: 5.61 HP @ 7200 RPM
Cold Air: 5.7 HP @ 4600 RPM

Edit: I just clicked the link to make sure it worked... enter 1997, honda, civic ex

 

Well, those are just the max values and the respective rpms that the values were achieved at. So, with that said, unless there is a chart a values throughout the rpm spectrum for each of the intakes, it will be hard to saw definitively that one is better than the other at high, mid, or low rpms.

All that the stats, that Mr. Mobsta thankfully found for us, say is that the max hp gain the CAI gives is 5.7hp which so happens to occur at 4600 rpms and also that the max hp gain for the SRI is 5.61hp which occurs at 7200 rpms.

So, to answer your question with my opinion, keep the piping and get a oil-free filter, like the dryflow.

 

Damn, I wish these companies would just freaking publish the full dyno graph for crap like this. [:@]

will this fit my ebay pipe, which i think is 3" in diameter


so, with your average filter, does it need to be oiled, ie placing a film of oil over the filter surface area?

 

Your average filter will needto be oiled. So, if you have the CAI, it's a real pain in the butt to oil it all the time.

 

What oil do i need to put on my filter; some 3 in 1 from an aerosol or some WD40 or something?

and how often do i need to oil it?

 

Well, K&N makes a nice filter oil kit. That comes with a cleaner and spray on oil. I'm not sure what kind of oil it is, sorry. As for how often, it really depends on the climate and how much you drive your car. It could be as often as once a month. That could be extreme, but I suggest for sure every oil change (3 months, 3000 miles).

 

get an AEM dryflow and never have to oil it!

 

Here are the dyno's from k&n's web site.

Also, my cold air intake is not here yet so I still cannont tell my opinion on what I think is better.

 

LOL. Look at the cars they tested. They aren't the same year or model!!!!

SRI: 99 civic Si (B16, DOHC engine)

CAI: 2000 civic EX WITH Auto tranny!!!! (D16Y8, SOHC engine)

There's no way that it is fair to compare to totally different engines can call it the same.
