Yeah just like these guys have a "dyno sheet" available.

However, a CAI will give you more power.. Not sure if its as much as 8 hp, but its some.

 

I don't doubt you will see an increase but I think the manufacturers will either bend the truth or test in a perfect environment.

 

It's at 4500 rpm, which is believable. But, no one drives at 4500rpm ( at least not for very long, KABOOM ).

So arguing about that 8hp is dumb and buying the intake for more power is dumb. The spectre at least moves the intake up so it is more difficult to hydrolock.

 

Plus it looks cool.

 

True for you 4.0 guys... But us 2.5 guys see over 4500rpm every day

 

Ditto... it was just way louder than I wanted. Sounds like flipping the switch on a shop-vac in the passenger side floor every time you start the ignition... or at least my '01 XJ did. I've had loud sports cars most of my life, but this was just loud AND annoying to me. I pulled it off, capped the hole and reinstalled the OE air box. Sold the Spectre to another Jeeper. He's happy, I'm happy...

 

I have one on my 97, it is really loud inside. Also you cannot run this with a tb spacer with this intake, even with the tube chopped down. No mention of that in the instructions. I learned this the hard way as my hood is F'd from this product. Not happy with the product or product support.

 

Also no noticeable difference in power between it and the drop in K&N that I had before.

 

So, you're blaming Spectre for screwing up your hood? That's like blaming Mcdonalds for burning yourself with hot coffee.

How are they supposed to know you're running a TB spacer?

 

Did you call and ask them when you didnt see it on the instructions?

 

id like to get one of theses sometime in the future, but i have a few questions about it.
1- will it work with a bored tb?
2- wont that breather hose throw oil directly into your tb?
3- anyone running this setup with stock exhaust want to post a video so we know what kind of noise were dealing with?

-thanks

 

Unless your buying an aftermarket TB with a larger exterior diameter then stock, then no. A bored stock throttlebody will work just fine.

Breather hose shouldnt throw oil into the TB. I cant answer that for sure, as i have lots of blow by.... However the blow by wasnt effected in any way by my CAI, which is set up in a very similar way.

Noise shouldnt be all that bad. If you have road tires or a really quiet jeep it may be a little irriating. It wasnt all that bad on mine, and my filter was right in front of the hvac..

 

You can always spray some sound deadener in the cowl
But I'm telling you it sounds BA. It's kind of addictive and sounds like straight performance
You either love it or hate it. Cherokees aren't quiet anyway I can't even have a conversation while I'm on the freeway without yelling (early model xj)

 

I guess it depends on your year, but when I went f/my '96 XJ to my '01 XJ it was night and day difference in how 'quiet' the '01 is. When I added the Spectre the sound to me was not performance (as I've had Mustangs and sports cars most of my life)... but it sounded like I turned on a shop vac that was mounted to my passenger side floorboard. And that sound is much louder when the engine is cold and calms a bit when your rig warms up... however, it's still very, VERY noticeable and to me got really annoying! Depends on what you're after honestly. I have no disrespect for Specre and the products looks great, cleans up the engine bay nicely and does what they say it will. They also give a 'notice' in the instructions that increased cabin noise will occur. Just depends on what you want.

I'd rather hear that 'noise' and performance sound coming f/a nice exhaust system... not f/the 'shop-vac' mounted to my floorboard.

Not sure if you can hear this as my iPhone didn't pick up the sound that great, but you'll hear that sucking noise at startup... and it's more subdued in the vid than in real life

 

It is a pretty common mod on these, you would figure that they would at least make mention of it in the instructions. Yes, I did call them all they could offer was a refund on the intake if I sent it back to them. This was after I already had a hole chopped in my firewall and a dented hood. The system fit with the hood closed, but it was so tight when the engine torqued under load it smashed the elbow into the hood so hard that even the paint came off the topside.
