[QUOTE=BobIsAwesome;1492624]A bit of wisdom from my hold high school auto tech instructor: automotive companies pay good money to their engineers to develop an intake system. If they could be out-engineered by guys that sell their kits for a couple hundred dollars, why do they still have a job? QUOTE]

This is true but things could be better cause the factory is trying to please everyone. How many 90 year old women do you think want to hear the noise of their engine sucking in air the CAI amplify or a louder free flowing exhaust. just my 2 cents

 

I think they just pay them to get rid of noise from valve overlap. More money goes into creating tooling and dies for plastic injection machines...

 

I have one for $14 off ebay and it does what it's supposed to do lol

 

all these answers and no budy caught he was asking for one for a renix there aint two many out there for them most renix owners make there own all auto parts stores sell fittings to make them with the air cleaners

 

[quote=Moparguy45;1493324]Well, you're right. Rounding off things for a larger user base would probably nerf the performance down a bit. All the same, you can probably see how I would trust the jeep engineers over a couple pringles cans and duct tape. lol

 

A Ram Air Intake(largest filter possible on stock intake tube) will net a VERY noticeable gain in bottom end/off idle torque and response and could help during rock crawling. I have a Ram Air and Cold Air Intake... Cold Air feels substantially stronger on the top end. Just go buy a $40 Spectre Cone Filter and put it on the stock intake elbow tube..... More noticeable off idle then $300 kits.

 

I've been thinking of cutting through the hood and doing a ram air straight to the tb but I'm just not 100% on the best way to filter it.

 

Same here 14 for part 18 to ship total $32. Looks great , sounds great , & that's about all it does except make it sound faster not run faster.

 

all those regular cone filter intakes are a waste and just suck hot air under the hood

 

I picked up one from a older guy on craigslist. He didn't like the extra noise that it put out when he gave it gas. Anyways, I only paid $15 and it's a K&N with a fairly new filter.

 

I did quite a bit of navel gazing on this one. "Cold" air intakes do work minimally, see Jeep TJ Wrangler - Intake Shootout The Full Story On 10 Intake kits

I do have an ebay intake with "heat" shield. Though it is shiny and seems to add a little seat of the pants action, I have noticed a little splatter on the heat shield. Apparently an air box serves a purpose.

For less money I could have had a diy cowl cold air intake that offers some protection from the elements. See https://www.cherokeeforum.com/f67/my...snorkle-67919/

That's the way I'm going to go when I get a little DIY time. My two cents anyhow.

 

Who the hell calls a 10% gain in power "minimal" ?
