Re: Mopar CAI Installed 5.7 HEMI

I'm pretty impressed that HPTuner's interface works with the 2011.

The WK2 engine compartment is sealed better than those of a few years ago.

Even without the sealing, the air in my engine compartment is always quite a bit warmer than ambient, there is a lot of radiant heat from the engine as well as all that hot air being pulled through the radiator. There is just not enough air moving to cool things down.

Years ago we used to punch holes in the hood and connect hoses to route the cooler outside air to the carbs. How many shows have you seen where they cooked dinner on the engine while that are moving.

Anyway, the difference between metal and plastic pipes is dramatic as more heat is conducted through the metal pipe to the air inside as well as directly to the sensor than with plastic pipes. You wouldn't think it would be much as the outside of the pipe is just as hot (it is more uncomfortable touching a hot metal pipe than a hot plastic pipe), but in practice it is dramatic, even without relocating the IAT sensor to get a truer air temp reading.

Re: Mopar CAI Installed 5.7 HEMI

I guess I will just have to agree to disagree because it defies logic for me.

Re: Mopar CAI Installed 5.7 HEMI

My point is that it doesn't matter if it's plastic, metal, wood, or glass. They all will eventually get to the same temperature as the air around them. Metal will be faster to get to that temp, sure. The point I've had since the beginning has been that the volume of air moving through doesn't get any (or very little) increase from the material that the pipe is made from. It's more due to it sucking in air from the engine bay as opposed to outside air.

Personally, I put "Heat soak" into the same auto jargon category as "solenoid". It's a fun word that people like to use.

You're more or less correct here, but being an "OEM" part, the original question actually makes a lot of sense. An aftermarket part certainly CAN void a warranty claim if the part can be linked to a failure that would not have happened had the part been left stock.

Now, since this is an OEM "aftermarket" part - it makes a lot of sense to wonder if a failure brought on by altering the air intake system would be covered under warranty, since its Jeep's part.

My dealer said I'm still covered using the Mopar Intake. I know dealers talk shizz....but the guys at my dealership have been rock solid since the beginning. Especially going above and beyond with the Sirius madness.

Re: Mopar CAI Installed 5.7 HEMI

Installed the CAI last week and loving it so far -- improvements to throttle response as noted in the posts above. I also think the sound from the engine is better - eliminating all the plastic from the stock intake. I haven't seen any significant gains in MPG, but that could be because since the install I have been a bit heavier footed...

Yo Buck! I'm still loving it! It's probably just me, but the sound of the intake seems to get better over time. I notice the biggest difference when I'm in Sport mode. The filter seems to be staying somewhat clean for being exposed the way it is.

Re: Mopar CAI Installed 5.7 HEMI

Good to hear! I want to know who buys a Hemi and says "make it more quiet"? The sound is amazing
