I've got a 2014 LT RS edition. It's got about 45,000 miles on it. The gas mileage is amazing compared to any other vehicle Ive owned. I get around 35mpg highway thanks to the turbo. With it having a turbo I was entertaining the thought of putting a cold air intake on it. The car is all stock and I've upgrades all my other vehicles but wanted to leave this one alone to avoid any potential problems but thought the cold air intake would give it a little more power and hopefully add a little mpg but I'm worried about it causing future problems. i.e. Issues with mass air flow sensor. If anyone has any advice either in favor of or against and if it's worth it please let me know! TIA

You won't gain power or MPG without tuning the vehicle, but an intake will make the turbo related sounds much more audible than the stock one.

I've had a cai on my 2016 for a while asking with brisk racing plugs. I've noticed its a little quicker, but not a whole lot. The turbo whistle is very noticeable with it on there. I don't have a tuner yet though.

Have you had any issues with check engine lights due to oil from the filter sucking though and and getting on the mass airflow sebsor? I had problems with my K&N on my Silverado

No, haven't had a single problem. The trick is to oil the k&n filter lightly. I had a buddy that would over oil the filter and then complain when it clogged the sensor.

I"m looking for a hot air intake. I prefer complete combustion. I get enough cold air in teh winter time. That causes partially richer and incomplete combustion.

I notice more power in the summer then i do in the winter. I also like clean air.

Couldn’t agree more. The only affect it will have if any without Tuning would cause you to run lean due to the added air. Just buy a tune from Vermont Tuning and leave everything else stock, Brian includes an eco tune that increases your MPG.

Ticking.

I've got a 2014 LT RS and it makes a ticking sound that eerily resembles a valve tick that you get when your low on oil or have a bent valve. We bought it used and I cannot recall if it made the noise when we bought it or not. A couple days after we got it My wife accidentally had the tranny in manual and when she took off did not up shift and redlined it so I'm not sure wether the ticking is normal or if it started after it for revved so high. I have taken it into the local GM dealer but they just did a basic diagnostic check on it and never really gave me an answer when j asked if the ticking was normal or if any of their other Cruzes sounded the same. The car would almost be silent when it is sitting in idle if it were not for the ticking so can anyone tell me if there car makes the same noise or not? I bought and extended warranty with it so if it is a valve issue then I can get if fixed. TIA for any info.

1) Check for cracked/loose spark plug.
2) With engine running, pull dipstick out an inch or two then replace. If sound goes away when dipstick is pulled then this http://www.cruzetalk.com/forum/34-g...4-pcv-valve-cover-intake-manifold-issues.html

Although your wife wound it up till the rev limiter took over, she could not harm anything.......computer won't let it happen.
Now, if it was a manual and she downshifted at high speed (known as a 'Money Shift') it would be a different story.

All that aside, I'm confident you are hearing 'injector tick'.......the injectors make a fairly audible click when pulsing and it certainly sounds like a lifter if compared to a older, non port injected design.

Normal operation.

Thank you Rob! I figured rev limiter would do what it is supposed to to prevent damage but it doesn't help that I cannot remember if it ticked like that when we bought it. I don't think I actually walked around the car while it was running to listen for things like that. This is my first turbod vehicle so I wasn't sure if maybe it had something to do with the turbo system. When I put my ear down closer to the motor it sounds like it's coming from right under the bigger cosmetic valve cover. If it's a normal noise then I can finally stop stressing about it. Thanks again
