For the price of those two, you can pick up a nice intake.

K&N is worth it, ever since I got mine I don't have to replace it with OEM thus saving me money because you can just clean it yourself. And it helped with the performance a little.

I really didn't notice any difference when I had it centuries ago but if you're keeping the stock box I noticed a huge difference with the Spoon drop in filter. Now this is my input only if you're keeping stock air box setup. Gl

it really depends on what you want. To save money, its worth it. i went with the K&N drop in because i wanted the stock airbox over some shiny tube with a cone filter for the tsx. The K&N is reusable like a lot of filters on the market, which is great by the way. i also removed the intake resonator in the fender and added my own velocity stack. there is a thread on here called "better intake DIY" if you search on tsxclub. This mod is nice, but the horsepower gain and cool factor is minimal, and probably nicknamed as the poorman's cold air intake. now if you want power, thats a different story. the best filter for an intake for power is no filter, and the higher horsepower filters probably dont filter dirt like an oem filter. The Injen intake has really good reviews, and heeltoe has conducted an intake horsepower test over various intakes, so you can search for that too. If you want to do further modding for power, i would get the injen personally and pay that price. all in all, you have to pay to play or be easy and get the K&N drop in and not care too much about power.

Really, i've yet to find one for $95. I wouldn't do short ram as those are about worthless. I had a CAI on my old civic and it made a nice bump in mpg, i always got hwy mpg except the day at the track and it would hit vtec frequently.

I also saw the import tuner article where they got 7hp and 8ft lbs with just the ims and coolant bypass. Which was more then the injen cai added.

There is one in the for sale section for a $100. Spend a few more dollars and get something worth it.

Its a hassle to me even though you are saving some cash but a OEM is bout $20. You dont have to wait for the KN filter to dry(they dont recommend you using a hair blow dryer).

I think its best if you have 2 KN filters to interchange or just keep using OEM filter. Performance wise there isnt much but you would get a better engine noise with the KN.

I would say a drop-in K&N air filter is only worth it if you modify the stock lame TSX air intake & resonator.

The stock TSX air intake draws hot air from under the hood plus the resonator is a complete pile of restrictive & useless plastic.

While doing this plus adding a K&N drop-in filter won't add much power, your engine doesn't have a chance with the stock hot air intake & resonator.

Really ?? Oh cmon man )) Stock intake sucks from under the left fender , its a true cai design.

KN absolutely worth it 100%

If just dropped in = better MPG as its less restrictive for pumping losses. All of my friends confirmed better miles on hwy. As for power gains - we have bottleneck that is more restrictive for flow than paper filter itself - resonator. So if you want your 3-5 low end hp - delete resonator and enjoy nice growling sound with sexy scream on vtec )

On the North American TSX, the stock intake air resonator is located in front of the left tire, under the fender BUT the air intake is inside the engine bay in front of the battery.
The piping swings back under the battery, then to the front, then vertical in front of the battery.

It's a hot air intake. This may be different on the European cars.

Noticed no power gain or increase in mpg with my k&n. I think the filter element is WAY too thin for proper filtration.
Went to stock and havent looked back since
Better filtration -> less silicates in oil -> less engine wear

I choose engine life over crappy filtration.

Im running the DIY cold air mentioned above btw.

I have a K&N and an Amsoil filter (same as Injen cone filer on CAI) and both feel better and works better then the OEM. Now I have an Icebox filter coming and have no idea which to use out of the three. Leaning towards Amsoil (great company)
