91 Ranger Breather Performance Question

You're best off just leaving them alone. Especially with the K$N thing. It'll ruin your engine from the dirt it won't catch. The tornado thing is a scam also.

What is it with everyone and the K&N filters? The filtration difference is marginal at best and they flow better. The airbox and filter can improve air flow there by improving performance but on a 2.3L what would the difference really be? I don't know anything about the Tornado fuel saver?

You can convert from 2 to 4 wheel drive. I have a couple of friends that have done it with F-series trucks they either had all the parts or a parts truck. If you plan on converting I would also change to a V6 the 2.3L with

What the deal is that the filtration difference is not just "marginal" . It is great big. No better than an old oil bath breather to be exact. And the extra flow will not make a noticeable (in mileage or performance) difference. Anyone who thinks it does is just trying to justify being ripped off.

Agreed. Strange how marketing and "kids" can build something up - make something really in extruded plastic, and market it as extra h.p. Save your bucks and enjoy what you've got -

Thanks to all who set me straight on the breather performance. While I'm not a kid (42), I'm really only beginning to become familiar with the make-up and performance of gas engines. Guess I should have paid more attention in high school "Gas Engines" class!!

If you would like to see some air filter test results, including a K&N look here. It wasn't the best for filtration, but wasn't the worst either.
