I know there are threads out there about this subject, but could not find a definite answer from the ones I read. 2014 5.3 Silverado with flow masters already installed would intake increase hp and mpg enough to spend the $$$

Airaid MIT would be best bang for the buck. Same approximate gains as the others. Reuses stock box. In tests it shown 1-3 HP over competition on a 2011 5.3

I wouldn't pay for an intake in a naturally aspirated engine. gains are not high enough to justify the expense. just my opinion.

I put a K&N intake kit on my 98 partially because the fact that over time it saved money over having to buy a paper filter all the time. The K&N intake filter can go 100,000 miles before cleaning and I put over 60,000 on the filter when I got rid of the truck and it still wasn't dirty enough to need cleaning. Plus when I bought it I planned on getting a functional cowl hood and the top of the filter heat shield is open. You don't feel the HP, but I felt the throttle response was better. I just had to make sure the filter wasn't over oiled when I installed it. Some people make the mistake of not checking and then they have problems with the MAF sensor when I only had to change mine once on the 98 and I'm assuming it was just old age. The stock filter in the truck now can go 75,000 miles so no need to get aftermarket in my opinion, at least on a stock engine.

 

I have a Flowmaster Super 44 on my '14 5.3 and installed just the Airaid MIT tube so I kept the stock filter box while getting rid of the maze between the filter box and throttle body. It looks so much better and gives a lot more room to work on anything. I couldn't really tell any difference in MPGs or performance. If anything it might have helped throttle response a little, but nothing major since it's a stock filter. You can also get the JR kit from Airaid which is the MIT tube with a drop in filter, but I don't see that doing anything where you can feel.

totally my $.02, and probably in the minority, but I never liked the k&n system of oiling a filter cartridge. having a source of "oil", even if it is minuscule seems like it'll only result in problems.

 

a massive amount of r&d goes into the current intake system to make it quiet, efficient, and providing laminar airflow. it may just be where I am not in my life/budget, but unless you do intake with a new header/exhaust system and a tune you just aren't going to get any improvement you'll actually feel out of it.

CAI don't do anything really, because no matter how much air you get to go through the intake, the throttle body is only going to take what it can handle… Unless you put on a bigger throttle body the gains are going to be un-noticeable. People say they feel the gains, but I think they just think that because most CAI make a lot more bark then bite… That said, even I plan on getting the AirRaid MIT, just to clean up under the hood. You don't gain much of anything, but you don't lose anything either, it's a lateral move…

You guys need to see some of the data out there. Black bear did a nice write up on different systems. All had gains, some more the others. This test was done on a dyno not gut/butt feeling

There are a lot of test out there that state otherwise as well. Personally I don't know how much I'd trust a test performed by a tuning company. Maybe they are seeing an increase in power, but they are probably tuning the vehicle as well… Gains that you could probably get with just a tune, and not intake modifications… Cold air intakes showed gains in older vehicles like my 91 because the factory intakes were restrictive, but now manufacturers are designing better intakes and the gains you see from CAI are marginal…

Of course, the K2 has a redesigned inlet duct and the inlet duct itself seems to be where the aftermarket systems get a high percentage of the gains. There hasn't been any dyno tests that I've seen for the K2 OEM vs aftermarket. Given the subtle nature of this issue and the small horsepower numbers, I would not automatically extrapolate the tests that Justin did on an earlier engine to these new engines. And again, noise is not horsepower.

      The timing marks are ok, that is #1, you can turn it over until they line up and it won't change anything, the crankshaft turns twice for every camshaft revolution, I have always set up SB Chevs as your pic shows using a straight edge

      Someone's been here before.... There is a receipt for a 3-piece timing set, purchased earlier this year.   Is this picture something, or, nothing?   I have the timing cover off and my crank is perfectly TDC and the keyed gear's locating mark is dead on 12 o'clock.   The cam gear locating mark is also at 12 o'clock. Now, I'm not an expert, but all the install guides say the two locating marks should meet and be perfectly aligned when installing a timing set. The mark on the crank should be dead on 12:00 and the cam gear's mark should be dead on 6:00, and both marks should be perfectly vertically aligned.   I believe the timing gear is keyed or has a dowel that ensures it can only be installed on the cam in one position, so I have to believe the cam is out of phase somehow. At the very least, with a triangular bolt pattern, it can only be installed in one of 3 different positions.   Before I pulled the front cover, the truck was running alright, no service engine soon lights except an occasional P0172 / rich condition. Timing -16 timing at idle (should be +16), and total -35% fuel trim, two conditions I haven't been able to figure out.   In related news, my injector tested pretty well, wasn't leaking, but I had it rebuilt anyway, and it's on it's way back to me.         Along with this discovery, the good and bad:   Good: The oil pan seal appears undamaged.   Bad: -The timing cover has been reused, and the positioning dowels have been broken. That could explain some of the leaking. -Some kind of white paste or grease was used to try to seal the oil pan seal and timing cover (since wiped off..). -Then, someone globbed silicone all over the front of the cover and also buried the ckp sensor in it. But, they didn't put any inside the cover or use RTV to try to seal the oil pan seal with the timing cover (good).

      PF63 Oil Filters Going Away?

      The guy that owns K&P filters last I checked in with him has over 300,000 miles on his Dodge base Hemi using his own 35 micron absolute stainless mesh filter from its first oil change.    The GM study I've posted a dozen times shows the relationship in engine life based in multiples of base units, not miles or years. That is the base unit is the number of miles the motor ran using the reference filter efficiency.    The above two paragraphs dismantle anecdotal arguments IF one changes oil often enough to prevent particle formation and the motor is in otherwise good shape. That is not full of silica (no air filter) or suffering a metallurgical issue that is not part of the lubrication discussion. Poor heat treat in example.   Data from UOA's I've reviewed from more than a few engines can show remarkably broad variations in oil cleanliness using the exact same filter over the course of an engines life.     Lastly there is the common sense of it. Wear debris WILL circulate the engine BEFORE it ever sees a filter in route to that filter and WILL harm the pump which NEVER sees filtered oil.    Alpha question then becomes, given the facts, how long do you believe is a reasonable service life from a vehicle you are certain you will not pass down? That is the junk yard will be it's resting place when you're done with it? (the moral issue most don't care about).    Omega question is then how diligent are you prepared to be in general mechanical, air & oil maintenance? Preventing particulates and keeping them sufficiently dilute; preventing the precursors from generation, amalgamation and precipitation.    If I get a good look at the engine bay of a vehicle I have a fair idea of the owners commitment to the inside of the power train. That 30 micron WIX is still more efficient than a sieve.

      It also depends on what criteria someone is using for “best” when talking filters.  Are we going off best efficiency?   Best quality/QC?  Etc. because the two may not mutually exclusive.

      They’re not the same wiz as 10-15 years ago.  QC has fallen pretty hard.  The XP line was never good though in the first place.    https://bobistheoilguy.com/forums/threads/wix-filter-rusted-through.386492/post-6991372   https://bobistheoilguy.com/forums/threads/i-ve-used-my-last-wix-filter.27299/   https://bobistheoilguy.com/forums/threads/looking-for-a-better-replacement-for-wix-51258.403977/   https://bobistheoilguy.com/forums/threads/convince-me-in-using-the-purolator-boss.401537/post-7420147   the forums are littered with posts and examples of not great wix filters the last couple years
