CAI vs Short Ram...an un-scientific approach...

Due to decisions made by AutoGuide.com, this site has ceased to be about the car, the people, and the community and has now turned into a commercial, corporate money grab.

That is not what I signed up for back in 2003. I am about connecting with like-minded individuals that share the same passion and commitment to the Legend.

I refuse to enforce AutoGuide's rules, and no longer can I participate here while they rape what was once a great community-based forum.

I am leaving to the new site and I am taking all of my contributions with me. They do not belong to you they are NOT your intellectual property per your TOS (a screen shot can and will be provided if needed). They belong to ME, the original author. And as the original author, I am hereby publicly stating that YOU DO NOT HAVE MY PERMISSION to go into your cache and restore my old threads and/or contributions.

Maybe someday I'll return...when the traffic here has died to nothing and you abandon the URL...but I will only return when this forum is no longer owned by you or any of your cronies.

It's been a great ride guys...see you on the other side.

Nice writeup. IMHO it should be a sticky.

That's what I have on mine. I bought an OEM K&N filter and decided I still wanted some of the benefits of CAI.

BTW I know this is way off topic but do you have a write up or parts list for an auto trans to man trans swap?

lookin cool

Hey nice, I vote keep the PVC, those elbows are pleasing, kinda doubt it will deform due to heat. When bending PVC electrical conduit one has to heat the crap out of it.

Do you worry about rain with cai? It pisses here in the winter.

Does it prolong engine warm up in cold weather? My car does 80miles/week of short trips in the burbs, I'd rather it warm up sooner rather than later.

What filter to use? I thought K&Ns are the way to go, better filtration and flow than paper.

I was once told the best is a conical filter crammed into the stock box, I fail to see how that would be better than a drop in K&N.

Any thought on the above?

cheers, Jay

yes my front bumper is in need of paint --- but besides that ... k&n drop in in the stock airbox with cold air coming straight into it via the front of vehicle (rammed air so to speak), & a friend of mine with an injen air intake would always beat me by about 1/4 to 1/2 a car b4 i did this ... i shit you not it is now the other way around. he paid $180.00 to get under the hood air, i paid $40.00 for the k&n & less than 10 for the aluminum 3" dryer hookup pipe & used a plastic piece from my yard blower that i will never use anyway. cheap or whatever you may call it, the power increase IS noticable & proven & it DOES give off a nice growl under the hood

Nice writeup. Couple of questions: first, exactly where does your CAI end? Second, what are you using for filtration? Thanks...

~I do worry about rain because there are some places in my area that are notorious for flooding come the first heavy rain. I know for a fact that my CAI will only be protected for so long by the splash shield and I've seen way too many horror stories on car forums...I know I could get a bypass valve, but I'd rather be safe than sorry...my next experiment will test the air temp difference between the CAI and cold air routed into the stock air box.

~I think that ambient temperature would affect your warm up time more than the CAI. I've had this intake on for over a week now and yesterday was the first day I noticed a longer time to warm up...but it was 60 degrees out when for the past few months it's been in the mid 70s every single day...

~Yeah I am using a regular paper air filter for a 91 Prelude...I trust the paper much more and I knew this setup would only be temporary. And regarding the Conical shoved into the stock airbox. Nikhai has this setup on his coupe and it does work, the only problem is though that I believe the stock filter or the drop in has more filtration area...either way I've just never been a fan of oiled-gauze filters...like Ken said, its a trade off...more flow with less filtration

Yes this is the California CAI that Erik (body9599) did way back when...this is kind of what I am planning to do, but minus the hose in the fender well...if one ever has to go through a deep enough puddle, that hose might become a straw

My setup ends as most peoples'...in the fender well with the resonator removed (been removed for quite a while actually hahaha) and protected from the elements by the splash shield. Also I am using this paper filter....

Stock Filter for a 91 Honda Prelude


Its a great paper filter...like I said I'm not much into oiled-gauze and I've had this filter on the intake for my wife's Infiniti for a long time now and its still going strong...plus I have no gripes about paying $6.99 every other oil change to change it out rather than having to clean and re-oil....

Thanks for all the great comments guys!

Hate to tell you this man, but I have read in the past that foam is probably the worst in terms of filtration....

Question

What is the diameter of those PVC elbows, what size are those couplers, and where did you get them?
