3 Air Intake Questions

1. Does anyone have a preference in a cold air intake? I have a small K&N on my 4.0, but there's nothing sheilding the filter, so do I just have a hot air intake? Am I gaining anything (over the stock system) with this setup?

2. Also, has anybody used those Tornado Air things?? Are they really worth it or are they a marketing ploy?

3. Throttle Body Spacers. Anybody have one? Does it help or is is a marketing ploy? I've heard mixed reviews all day long. Please only comment is you've actually had or have one.

i have K&N air filter, the tornado crap, and a throttle body spacer.
To be quite honest, i don't know that any of it did much, if anything. The only thing i would consider again would be the K&N filter. Throttle body spacer i got for cheap, and the tornado thing i got for cheap too. Wouldn't buy either again.. JMO

Popular Mechanics tested a whole bunch of the power-adding gimmicks a while back, including the tornado, the magnetic fuel de-ionizer (or whatever that thing is), and several others. I'm pretty sure they all hurt performance, and one actully caught fire. IMHO there are too many other ways to spend money on a jeep; why waste it on something under the hood that isn't going to make any noticable difference?


edit: just found the article; tornado REDUCED peak hp by about 10%

I read that article too. They told you why it doesn't work too. The tornado is dogged any time I have read anything about it.

JP mag mentioned them aslo as crap. They aslo said that there is a following of people that love TB spacers but they don't do much...Then they did the "trail jammer" and with the spacer and intake alone got +2mpg.

I have an airaid on my 4.0 XJ and it does nothing for MPG but I would agree that the throtle is a little more responsive and a touch more power. If I had to guess at the power I would say 5.4609925 more hp

All that stuff is garbage. If anything , get a snorkel , ive even heard bad things about them restricting flow. Stock isnt that bad , a lot of research goes into stuff like that . I guess they took a break when they decided on the dana 35 though.

Don't waste your money. I just took out my AEM Brute Force Intake. The stupid thing is a vacuum waiting to hydrolock your motor. Use the money and get a snorkel, you'll get cooler, cleaner and more air to your engine. I recommend ARB. I have more HP with the ARB Snorkel than I had with the AEM.

Wow, that was a good article! Looks like the Tornado is not happening. As far as the throttle body spacer, I haven't heard enough things about them to add one to my Jeep unless I found one for $1...but then again a Wendy's chicken sandwich does sound kind of good right now.

Feeding a chicken sandwich to the engine would probably have better results than some of the things they tested
