Jeep: K&N vs Airaid

Both are good for what they are, save your money. Unless you have done some
serious modifications such as cams, lifters, pistons, etc.,it is a waste.
Some change their exhaust and intake and swear they are getting performance.
But, when measured on a dynamometer there is usually very little change.
Think about it if it was that simple why doesn't the auto makers do it.

For that matter why won't the manufacturers of horse power add-ons guarantee
their claims? They all tout more and better performance but they are like
an alligator, all mouth and no ass.

The only true way to gain HP on a computer engine is to remap your computer
for better performance. I bet my friend with a remap my 04 TJ would have
more and better performance than his modified 04 TJ. He had about $800.00 in
exhaust and engine modifications that he did himself. He laughed and said
how are we going to prove it, I said a dyno test and the looser pays for all
the testing.

I paid a local speed shop to remap the OBC and the same fellow did both our
DYNOs for $175.00 each. The guy charged me a $150.00 to remap my TJ and he
said with better performance that the gas mileage would drop by at least 1
or 2 mpg. After all said and done I had 7.5 more horsepower and 3.2% more
torque at a lower RPM than my friend with an overall increase in HP over a
stock engine by %18.

So for a $150.00 vs. over $800.00 in modifications my TJ was better off.
Save your money and have a remap done or buy the remap tool for around
$400.00.
