Hello. I have an 89 f 150 with a 4.6L inline 6. Thinking about one of those K&N cold air intakes, but wow are they expensive. Any opinions on the advantages vs cost?

 

I've quite often heard that the 300 I6 and 460s come with better stock airbox systems than aftermarket "cold"(warm underhood air) intakes. If I were you, I'd stick to the stock setup.

 

get a good complete tuneup with motorcraft parts.

that would help more.

the stock set up is just fine.

 

i feel that way more and more everyday, good call

 

You already have the inlet tube that 302/351 guys look for. Keep it stock and do what Quicklook said.





btw, can i have your inlet tube.

 

yeah stick with what u got, i have a drop in k&n filter and love it, and plus if u put the whole k&n setup you will be drawling warm air in

on top of that the 300 makes its power at such low rpm's that a cold air intake (which usually helps higher rpm's) would be pretty pointless

i got a 351 im lookin to boost the power, at least the low end of er, and i can get a 300 inlet tube for dirt cheap. how do i convert one of them 300 i6 inlet tubes to fit my truck? or do i just replace mine w/ the ones off a 300?

 

Thanks for all the info guys. Really appreciate it.

 

get the inlet and it goes right on with no cutting or anything.

 

I agree the I6/460 tube is the way to go.

Adding a better flowing filter is also a good idea.

The CAI is a joke, no matter who made it. I don't know why they are called cold air intakes anyway, since they suck in warm air from under the hood. I had one and it was worthless except for sounding cool. My truck didn't run as good and got worse fuel economy.

 

Just a bit of a thought provoker, is there anyway a guy could take the 300 I6/460 intake and make it better and/or replace it with a newly plumbed system in the same place?

 

no real benefit to doing this.

 

question, is there a benefit to taking out those cone plastic things in the 460 air intake tubes? I was told it is good to cut them out so i did and if it did anything it gave me less HP instead of more.

 

so i have access to an intake tube and box from a 92 300I6 truck for $10 ....

Its a little bit of an upgrade on a 93 F150 302 ?? just the tube that goes from the throttle body to the box ?? or the box too

thanks

 

No, you want just the inlet tube. It draws fresh air from behind the grill and sends it to the airbox.
