Is a K&N drop in worth the 50+ bucks or not ??

I am thinking about buying a K&N drop in filter for my 2.5 4 banger , but i hear mixed reviews on them. Is it worth it, will it help any performance/mpg ?? Or would it be better to just stick with a decent paper filter. It sucks there is not many cold air intake systems out for the 2.5, and would one of them even make a difference ?

the filter itself makes very little difference
you can buy a lot of good paper ones for $50...

Would have to agree with neither one being worth it. I have my oem intake with a k&n and couldnt tell a bit of difference in performance. Now I have a banks cai and it makes a nice whistling sound around 2000 rpm's but nothing noticeable on the power end. I would just stick with the oem intake and paper filters. Just my .02

If you can afford $50 + $10 for the recharge kit, I would go for it. $60 for an air filter that has a million-mile guarantee, kind of a no brainer. Even if it has not performance gain, depending on how long you keep your Jeep, it would be worth it in the long run.

Get the filter and recharge kit from Amazon,

it should be less than $50 and to me it is worth it. Not for any power increase but for gas mileage help.

Also, you will probably never buy another air filter as long as you follow the instructions and clean it once in a while.

Don't buy it for the HP gains or the gas mileage increase, cause it helps with neither. Buy it because of it's ability to keep dirt out of your engine. I'd like to believe that the improved filter media and it's ability to keep contminants out of your intake is worth it. You might see a very, very slight HP gain if you can open up the other end (the exhaust I mean).

i have one in mine and do recommend it (i also drive a 2.5L)...

i dont like an open element filter but decided to just give the drop in a try since i read so many back and forth reviews...

i picked it up for 30 bucks (just look online, you'll find one) and put it in. I didnt buy it expecting some crazy hp gain or mpg gain or anything like that. I basically bought it to have the motor run smoother.

I have zero regrets buying it. I could go up hills without downshifting where i previously had to without it, could take turns in 3rd without bogging and going into 2nd...and overally it just runs smoother.

Before i put the filter in, i took the intake tube off and checked it out...cleaned it...etc. Then i put the filter in and drove with it for a year so far...took the tube out again, and it was still clean as can be from before so for me it doesnt let anything "extra" or "harmful" into the motor. I also offroad whenever possible and this is my dd...

Just buy one and give it a try...if you dont like it, you'll sell it and lose maybe 10 bucks on it...
