My next oil change and filter is comming up and I was considering just buying a K&n to replace the stock filter. Has anyone done this? Does it really give you more pep? Does it change the sound? Thanks for your input..there 20 bucks more then a generic filter and would love some opinions!

If you are going to pull away in second-gear then I doubt you'd notice a difference

Hehe, i'm not going to do that anymore (Traffic was pissing me off ) anyways, can anyonej ustify the extra 20 bucks this filter costs?

No they won't give you any more power and the only thing you'll notice is that it could sound slightly louder as it lets more air through - if you were going to sort out your induction then it'd be better to buy a fully enclosed system with cold air feeds

I bought one and haven't noticed a difference at all. The good thing is that I never have to replace it. Just clean it out from time to time...

[Lkemybab]

I think that you would only see a difference if you installed a whole new intake and filter...

[rarpAcconavox]

A cold air intake would make a difference, but the filter alone doesn't create any noticable performance or efficiency increase. Not on my car at least.

adds a couple of horse power. but if you have an airmass sensor it can mess with the engines management system.

Would it be a problem on a newer car? And how would I know if their was a complication with it?



-> Also I have an aftermarket exhaust and I love the deep tone it produces..i'm excited for more airflow to add to the tone, well hopefully, but in theory more air = more sound, right?


-> would an intake system void factory warranty?

your probably better off with a good exhaust system it allows the engine to breathe better that will add a few HP too.

i wouldnt bother with an induction kit just get a complete exhaust system dont just get the big bore back box the whole exhaust needs to be changed to get better engine performance and if its got a cat well you can remove it but ur immissions will be effected but it will release some hp my mates ram broom handles into the cats to destroy them

What if you use this filter in a turbodiesel indirect injection engine? I live in Albania and it's very, very, very dusty. Will this filter be able to filter better than the stock one? How do you clean a k&n filter?

[Sthjrderfida]

Simple answer. No.

I assume u mean a replacement panel filter and not the 57i filterchargers.

Either way, neither will give you any extra bhp. You wont notice any difference either. They are used by idiots who believe what is wrote on the box but fail to realise the bhp gains is:

A: The max u will ever achieve
B: That "bhp increase" was prob measured on a Skyline R-34 Twin Turbo not a 1.8 N/A.

I really like K&N air filters. IMO it's a cheap way to add both a small amount of HP and it adds to fuel economy. That and you only have to clean them 1 or 2 times a year. I hear that even at full dirt capacity the K&N still flows more air than a standered paper air filter.

edit: to 3dfx... call me one of those idiots that believes it then. I mean I didn't get my car dynoed or anything but when you see your fuel economy go up 3-5MPG you kind of sit up and take notice that "hey this thing is doing something"

What??? more economy?

It draws more air in, more air = more fuel (hence the supposed bhp increase) so more air + more fuel = more mpg?

Ok..... [rolleyes]

[Qnpqbpac]

We really need a car nut to come in here and clear things up. More air = the fuel burns more efficiently = more fuel economy I thought that was common knowledge? I mean if you really get on it then yes you will use more fuel but under normal driving conditions you are using the same amount of fuel but it is burning much more efficiently hence better gas mileage.

[rarpAcconavox]

More air means that the fuel will burn quicker and will produce a more efficient engine (up to a certain point of course). Atomizing the fuel better will also help.

[FelixQY]

You'd never buy a K&N or any other aftermarket filter for economy. Buy them to save on replacement filters or to go green(ish).

3dfx is right - more air in causes the ECU to add more fuel. The car will be (slightly) better in gear - but you'll use more fuel - despite what the box says.

That's marketing for you.

Having said that I've put one on my last two cars - but this one's def. not getting one.

which is confusing considering I watch my MPG very closely and when I installed a K&N on my last car my MPG rose about 3mpg over the course of 2 full tanks. This was calculated form a full tank to when the low fuel light comes on (comes on at 2gallons left every time). Driving the same distance to and from work every day at a constant speed (95% of my commute is highway). So I dunno, everyone has to make up their own mind I guess but for me the K&N did help with fuel efficiency over a clean paper filter.

Im glad someone on here understands how an engine works.

Assuming you have a Mass-air system. If you have a speed-density system (older cars), then it might help. Some.
