I have an 88 f150 with a 302 5 spd and i dont know whether to get the system or not would love some advice along with others that have them and how well they work

 

COMPLETE waste of your money.

 

Bingo...

Here's the scene....

(You're ordering a $300 K & N Filter kit)
You get it in the mail, throw it on.....And then drive the truck PISSED.....Because its no better than before...

(Dude that sold you said K & N unit is laughing himself sick, couting the $50 bills you sent him....)



Simple as that.....Use the money elsewhere...

 

Everyone will tell you that they're a waste of money. I'm going to confuse you by playing the devil's advocate. I put one on my 1990 with 302/5spd and I was very happy with it. I could tell a difference that was IMO worth the $220 I spent on it at APC. In my experience K&N has an amazing product and I will always run their stuff. One of the first things I did to my new '89 was to buy a K&N drop in filter because I already have the fairly well engineered 460 air box that has a semi-ram air sort of design to it. Once again, I can tell it's breathing easier even with just the drop in filter. Bring on the flaming..

 

Nope. I had my exhaust shop bend me some 3" tube for a $40 total. Then bought an 11" cone filter online for like $40.

 

Did you insulate that somehow? I would think that would get pretty hot.

 

Its plasti dipped which helps a little. It gets pretty warm though. But not as bad as bare metal did.

It was going to just be a temp setup but I got side tracked on it.

 

Here's the test you do on one of these old SD trucks before buying any intake products. Go out and completely remove the tubes between the air box and TB and take it for a drive. Ignore any difference in sound and try to determine if that makes any real performance difference.. like time the truck 0-60 before and after. If it does make a difference then consider the fact you just got that for free and that an air filter of any type simply cannot produce any better results and see if you think the K&N is worth it for your truck.

 

Is it worth letting more dirt into your motor? Remember it let's more air in and let's more dirt in. And a oiled filter before a maf sensor...if truck has one is a no no as well.

 

You're suggesting that the OP drives his truck around with no filter because it's cheaper than a K&N? I don't know about canada but the states have dust, blowing sand, leaves etc. that could blow his engine and would cost a lot more than a FIPK.

 

Bingo....No use wasting money on stupid chit....

He's simply making a point...

Again, Conanski's only proving a point.....If nothing else, put the filters directly on the throttlebody...Ya happy now?

 

I really don't get this logic. Do you think that leaving a dirty clogged up filter will let less dirt in?

K&N has a response for you;

24. More airflow means you are letting more dirt through, right?

No. Filtration testing measures the percentage of dust retained before the filter reaches a terminal test pressure, often 10" of restriction above initial restriction. We use airflow as a simplified term to explain a more complicated physical process. The more precise description is restriction: K&N air filters create less restriction which helps an engine run better. An engine will only use the air it needs and our air filters do not result in an engine using more air than necessary. Rather, they result in the engine experiencing less restriction. The terms airflow and restriction are inversely related. Our air filters provide either less restriction at a fixed airflow rate; or more airflow as a fixed level of restriction. In neither case is more air being used than necessary.

 

thank you lvin

 

That would make me happy and luckily K&N makes a kit that pretty much does that for you, that's what i'm talking about

 

I'm tryin' buddy

By the way, has anyone that's professing the K&N to be junk put one on their truck and tried it? (not your buddy's truck)
