I just bought a 94 F150 with a 300 and a 5 speed. Any simple things to do to get a little more power? Like a K&N filter/cold air intake? Do they make them for this application?

Garrett,
Make sure your I6 is breathing good, ie. free flowing exhaust through the cats and muffler. If not, correct this. The 300 is a poor breather. On the other end, a K&N filter pack will help if your truck is MAF (mass air flow) equipped. If you don't have a MAF sensor under the hood, your truck is speed density (don't remember what year they went from speed density to MAF) equipped and the K&N filter pack won't do a lot of good. The MAF sensor reads intake air flow and helps the computer adjust fuel mixture accordingly. If you've got a speed density truck, just go for the K&N drop in air filter instead, don't waste your money on the filter pack (didn't do beans for my truck). You can also switch to a hotter ignition system, Jacobs or others. This will run about $500 but you will have more power and pep and better mpg. Another thing you can do is switch to the Bosch Platinum four plugs, or just side-gap a set of good, cheap Autolite or Motorcraft plugs (search the main page of this site for "sidegapping" for more info on this). This simple modification got me the most bang for my buck ($8 and some time in the workshop). I've got a 90 F150 with 300 I6 and was getting about 14 mpg in town and 17 on highway. Sidegapped and installed a set of Autolite plugs and now I get 16-17 mpg in town and 19-20 on the highway, plus truck is peppier and runs smoother/better. Sidegapping does shorten plug life by about one-half though...but plugs are cheap compared to $1.75 gallon gas, IMHP.

 

How can I tell if I have a MAF sensor? I am used to older trucks without all this computer stuff, as you can tell by my username.

I have never heard of sidegapping before, I am reading about it now. Sounds interesting.

Thanks

Your 94 is speed/density. That does limit you a bit. There's been some discussion on this both here and on the BB at www.cliffordperformance.com. There's still a lot you can do, especially if you are willing to have a new chip burned.
