Air Intake

Hello Everyone,
I am looking for a good intake system. I have been looking at both short ram and cold air intakes. My 95 Honda Prelude Si is my daily driver and so i was wondering what you guys recommend getting, short ram or cold air? I was looking at getting (AEM 21-405P Polished Cold Air Intake System) yes or no? Thank you.

AEM V2 supposedly has proven performance. Your best bet is either:

Stock K&N Drop-in filter (keep stock air box and remove resonator if you're looking for sound)

Type-S Intake

AEM V2

Re: Air Intake

Please consider these points before you waste your money.

1: Your stock intake is a CAI (cold air)intake .
2:When you consider that a 4cyl engine only has 1 intake runner demanding air at any time combined with the fact that the air intake piping is much larger then any single runner , the stock intake is not restrictive.Some types of intakes can effect the tuning of the engine by raising the engines power band somewhat given a little more top end power at the expense of mid/low rpm torque and throttle response. This is not a good trade off when you have a 4cyl engine trying to move a 3000 lb car.
3:You can somewhat improve throttle response and thus improve mid rpm power by getting a OEM TYPE S intake that uses a 2nd air box just before the throttle body to influence the tunning of the engine air pulses in a positive way.
4:The stock intake has a valve at its input that gives the ecu the ability to tweak the intakes response an effectively tune the intake for the range of rpms your operating at which helps a lot with low/mid rpm power and fuel economy. .No aftermarket intake does that.Also with the prospect of gas prices going as high a $4 a gallon,the stock intakes ability to increase fuel efficiency by speeding up the air flow at low/mid rpms by shutting off one of its two an air passages at its input ,is more valuable then ever.
5: For a sound that has a lower pitch while not turning your intake into cop
bait, all you need to do is plug the passageway leading to the resonator box thats below the air filter box. Just temporally remove the funnel at the bottom of the air filter box and look down the hole in the bottom to see what needs to be plugged.

Check out this write up below from a UK web site.





Here is where you can get a TYPES S INTAKE.

Re: Air Intake

Thank you. I bought my prelude with a cheap short ram and cone on it so i will have to buy the whole stock intake system with the k&n filter. thanks for the link. will i get as much power with the type s intake vs the aem v2? it looks like they are going to be about the same price. also i have been reading through multiple forums today and i was wondering if the type s will hook right up to h23a1 throttle body/intake manifold?

Re: Air Intake

Honda has put some decent engineering into their intake systems but bare in mind that fuel economy is more important to them than max peak hp. Apart from the stock system (with resonator) reducing noise, it is restrictive if you are aiming for peak power.

A simple test, have your intake in stock condition and do a pull (second gear up a hill in a high speed zone) and then remove the rubber connector underneath the stock air box that connects to the resonator and do another pull. The difference is night and day. I will never be able to revert back to the stock resonator, its like breathing through a straw (great for low end torque but starvation at the high end).

I have tried many intakes, mostly DIY. Stock airbox (with filter) and no resonator; stock air box(no filter) with pod filter fitted to its outlet where the resonator bolts on; 3' short ram leading into the stock air box with stock filter or with the pod either in the airbox or where the resonator bolts on plus the conventional short ram and CAI. CAI works the best, best noise generated and best peak rpm. Stock intake minus resonator is decent but somewhat silent.

Here is a pick of stock airbox with pod inside and 3' short ram pipe feeding it. Aluminum gives more noise than the factory plastic and looks nicer.



So you can play around with the intake, and you don't have to spend heaps to get a decent unit. Id say your better off converting what you have to a cold air intake providing you live in an area where floods don't occur frequently. Type S minus resonator would also be good but I do believe its been dyno proven to not yield the same peak power as say the AEM V2. What you really need to figure out is what you are after, if you want fuel economy stick to Honda's stock system, if you want a higher HP figure (and loose some low end torque unless you get a tune) then go aftermarket!

Re: Air Intake

Not that I can give a real review, but I just bought the AEM V2 myself, it'll be here sometime this week.

Bare in mind I wasn't working on a tight budget and had the 300 dollars to splurge. I haven't heard anything bad about the intake, on its release there was a rubbing issue but it's been fixed.

The AEM use's the concept of CAI and Ram into one, sort of. The RAM is usually for high end power, while the CAI is more for low end torque. The duel chambers, going from fat to skinny, with the skinny extending into the fatter piping, allows both concepts to work at the same time. Mind you, you wont get the best of both worlds, but a mix in between.

Also the way its design, and the sound waves it gives off is also suppose to increase the air velocity or something another. Its suppose to sound wicked, another reason why I picked it up.

I'm running the stock intake with K&N filter atm, resonator too.

Re: Air Intake

Thank you. I think I am going to look in to getting the type s intake with the superior stock set up for a little more power and decent mpgs. i just need to figure out if the type s will hook up to the h23a1 without any special fittings etc.

You've got that backwards. CAI is for mid-high end power, SRI is for low-mid range power and improved throttle response.

yes it will fit the h23...but depending on what type of strut bar u have, it will not fit...strut bar might be on the way...plus u would need to add a return port for a vacuum line on the intake itself...

Re: Air Intake

i dont have a strut bar at the moment so that wont be a problem. as for the return port for the vacuum line, what/how should i go about doing that?

Re: Air Intake

ok i want to get the type s intake with the drop in k&n filter and i have the first link to get the top part of the intake but i do not have any of the stock intake with me. i need to know what else i need to get to make the type s intake fit and work. help please.
