in my honest opinion, an aftermarket filter is bad news. If you think about it. if you are letting more air pass through the filter - less restrictive - then you are filtering less particles. The amount of performance increase is not worth the potential problems. I used to swear by K+N but after much research, i stick with puralator. Fram is garbage - look it up. :talk2much Everyone should note, whether they agree with me or not, that you must remove the airfilter cover from the intake tube when you change the filter, not just open the clips. if you do filter change incorrectly, the filter will not seal and you will suck unfiltered air into your engine - path of least resistance.Rumplecat said:I was looking to put a perfrormace air filter on my mada but I was wondering what I should go with? Do they help out fuel economy any? Any help is appreciated.
I don't know how to read charts, but does that mean the K&N filter is the best?Cillyone said:Some test data on filters. There is no free lunch.

Actually the worst. AC Delco is best. I'm sure there's more to it, but that's what the chart says. Go figure...ggeorgie said:I don't know how to read charts, but does that mean the K&N filter is the best?![]()
This means that AC Delco is most restrictive hence filters more dirt. Also means K&N is least restrictive means filters less dirt (less restrictive means more air flow, higher horse power).ggeorgie said:I don't know how to read charts, but does that mean the K&N filter is the best?![]()
Doesn't that means, less restrictive, more dirt into your engine?FL_Crushin said:This means that AC Delco is most restrictive hence filters more dirt. Also means K&N is least restrictive means filters less dirt (less restrictive means more air flow, higher horse power).
You give up cleaning capability to get higher airflow. It's give and take. We're talking about very small particles.
Yes, kinda. We are talking about particles smaller than household dust. Not shovels of dirt from your garden. Now just imagine 10 particles of dust... how about 100 particles of dust going into your engine cylinder, then it gets exposed to an 800 degree explosion. How much damage do you really think it's going to do. Probably none at all. So it really isn't that big a deal. Those charts are a sales pitch by AC Delco, if you couldn't tell, that's all. They make K&N look all crappy, but if they were so bad, why do some many race car drivers use them on their very expensive engines. Don't see many AC Delco stickers on dragsters.ggeorgie said:Doesn't that means, less restrictive, more dirt into your engine?![]()

Crushin, not a good comparison, those racers are not trying to get 200k miles out of their engines like I am. And race engines blow up before they get a chance to wear out and besides I don't have a pit crew to change motors or sponsors to pay for it.FL_Crushin said:They make K&N look all crappy, but if they were so bad, why do some many race car drivers use them on their very expensive engines.

That is a valid point, but I guess it's like choosing synthetic or regular oil. My dad ran his Datsun 510 for over 300K miles with regular oil. The NJ road salt rusted it out before the engine broke down. I guess what I'm saying is that either way it doesn't make a whole lot of difference. But sure, if you want to ensure you have the cleanest environment for your engine, go with the regular pleated filter. So what kind of air filter do you have in your house. I hope its the high efficiency pleated filter. I would hate for your car to outlast your health.Cillyone said:Crushin, not a good comparison, those racers are not trying to get 200k miles out of their engines like I am.

Again another good point. For the most part I would say that most mass produced engines are designed for durabilty vice perfomance. For example I've seen where some reputable companies like to run there engines at full throttle for 24hrs or even longer just test to the strength of design. Grant it the engines scrafice weight, performance, an efficency for this trait but when you can honestly say you won't need a tune up for 100k it makes a great selling point. :2cool:FL_Crushin said:That is a valid point, but I guess it's like choosing synthetic or regular oil.
