Anyone know about "dnamotoring"? It appears they have a CAI that's less than 60.00 (ebay, free shipping). I found this on their website: 99-06 Chevrolet & GMC - Short Ram Air Intake - Red. I'm not sure what to do with it ... it's just 60.00 ... and I understand the saying you get what you pay for. I really like that Injen PF7050P for my truck, but couldn't help to wonder.

This post is great. Just made up my mind about intakes. For sure going with the k&n drop in and airaid intake tube.

I am thinking now that the K&N CAI I have on my 2003 Silverado is contributing to the truck running hot in the summer while towing my racecar. My brother has an identical stock 5.3 in his 2001 Sierra with the stock airbox and a drop in K&N. When towing, his truck will run 20-30 degrees cooler than my Silverado. I think the metal tube and splash shield is heating up the air combined with all the hot underhood air. I may go to a different system next year. Just wondering what anyone else thought? BTW, the truck runs cool, except when towing on a 85+ degree day.

I use to experience the same issue on my SRT-8 jeep when I was drag racing her, after some research and talking to my local speed shop about this problem we found a soultion. Theres a manufactor that makes a type of powder coating thats heat resisant/dispersing(kinda like jet hot coating for headers). We took before and after temps and the results were astonishing which resulted in about a 48* overall drop in temp on the intake piping. Might be something you want to check out.

Thats actually a really good idea, you could try using headers wraps, or summit makes a pretty cheap starter wrap, but you'd probably need to buy like 3 rolls

These intakes can lean out the fuel and cause your engine to run hotter. It's not the actual air heating up the engine. If its hot out and your under load and the engine is in a lean condition it will also pull timing out and reduce power and inturn you push the pedal for more power so the engine works harder thus creating more heat.

I was looking at super charger kits that boost to 425 hp on the 5.3l. The Hennessy kit uses a drop in K&N and used the stock box with a new tube obviously. I think our stock boxs are fine for our 300 hp motors.

It's not the box that's the problem, its the restrictive ducking with all the built in silensers. And they reuse the factory intake box to keep cost down. I have a 6.2 and a 5.3 both have CAI which is proven to make a little more power by smoothing out the incoming air and increasing volumetric efficiency. It's basically personal preference and how you plan on using your vehicle. I'm doing all the small stuff first before I bolt on the TVS 2300. My goal is 500hp to the tread and being that my engine is only 130hp shy of 500hp at the tires I believe that with the addition of the LS9 cam and a Maggie I will probably bust the 500hp easily. And multiply the hp number at the tires by 1.2 and that's some serious flywheel hp. Will make a nice little sleeper.

So I have a question, related to my previous CAI experience with my previous car. Do you not get CELs when adding on an aftermarket CAI on GM trucks?

I used to have a 2004 Mazda 6s before i got the 2011 Silvy Z71 5.3. I bought the MAFci system from Custom Performance Engineering (www.cp-e.com - I highly recommend these guys they know their stuff). This system was not only a custom engineered CAI intake pipe, high-quality filter, etc., but also a air-fuel mix customizing 'chip'. You had to wire it into the car's electronics underneath the steering wheel. You HAD to do something like this (basically re-route the sensor to computer signals through a custom mod-chip), otherwise you would get CELs (check-engine-lights) due to the increase in the airflow and change in IAT. The chip not only prevented CELs, it customized the air-fuel mixture to maximize the gain in HP. Mazda actually put the 6 out of the factory running too rich, so there was a lot of gain to be had (18HP at the wheel and similar torque gains, verified on numerous dynos). Sounded FANTASTIC too...

Still had to clean the cone filter alot, and clean the MAF sensor, plus the TB every now and then...but thats a given.

So there it is...CELs with CAIs or no?

I put a K&N 63 series on my 2011 Silverado 5.3 with no other changes and it didn't throw any CELs.

Lately I've been hearing nothing but bad things about the K&N air filters?? Something about a lack of pressure because of the extreme amount of air flow and dirt getting in the engine. Anyone having problems with this?
