"Should have bought this when i purchesed vehicle. 1st week saw 25 mile gain on tank of gas. 45 min to install. Truck is more responsive. little loud on heavy excelleration, but quiet as stock at normal cruise." —Patrick B from Glendale, AZ bought a K&N 77 Series Metal Intake Kit for a 2003 Toyota Tundra, 4.7L V8.
"As soon as I installed the K&N 63 and took my 03 Tundra out for a test drive I was amazed by the increase in power and hard core rumble of the 4.7L V8. The installation took 2 hours and except for some really terrible photo's in the directions got it done with no problems at all. I would recommend this K&N to every Tundra 03 driver out there. Its definitely puts a new dimension into the performance of my truck. I am taking a 2000 mile trip in September, so that will be a good test for any increase in MPG, being that I'll pretty much be at cruise'n speed most the way." —John E from Auburn, CA bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2003 Toyota Tundra, 4.7L V8.
"I've been running the 63 Series Air Charger for about 2 weeks on my 03 Toyota Tundra. I can't say that I've been overwhelmed by any fuel economy improvement, but I have definitely noticed an increase in power. This won't push you back in your seat, but it helps. Also, the extra noise from the hood is awesome. You can hear it breathe and it just sounds meaner. Definitely recommend it." —Scott P from Santa Barbara, CA bought a K&N 63 Series AirCharger High-Flow Intake Kit for a 2003 Toyota Tundra.
"The instructions are bad. They don't tell you about disconnecting the battery and my truck has 3 hoses not 4 like they showed. K & N site was very helpfull with this. Also the big intake opening on the box which you are to put a strip of rubber onto so it will seal against the inside fender wall would not fit on the lip of this opening. It was WAY to thick for the rubber to side onto. I had to use a dremmel tool and grind away alot of this plastic to make it thin enough. No change at all in MPG. Does sound very nice. Overall I'm happy." —Alan T from South Windsor, CT bought a Volant Cold Air Intakes for a 2003 Toyota Tundra, 4.7L V8.
"Very good product, but I wish the company has complete procedure of installation and post it on their own website, make everybody's life easy." —David C from Whittier, CA bought a Volant Cold Air Intakes for a 2003 Toyota Tundra.

"All my friends have volant cold airs on there sicky trucks and demanded that I get one for my 03 Toyota tundra. so like I always do, I gave in to the peer pressure and bought one. I think it was the best thing I could have done to my truck! It woke up and now has some balls I love it. Thank u auto anything for selling it at such a low price" —Brendon B from Midland, TX bought a Volant Cold Air Intakes for a 2003 Toyota Tundra, 4.7L V8.
"Was very easy to install, even for someone who does not have much experience under the hood. Took longer to take out the old airbox than it did to put the aFe in. Had some issues due to my MAF, and tech support from aFe was helpful, although I handled much of the troubleshooting on my own. Turns out my MAF was bad, and once replaced, all was good. Have noticed about 2mpg gains with highway driving, have not tested city yet but I will on next tank. Sounds awesome and compliments my exhaust well. Pick up off the line is noticeable as well. Great product from aFe, and I would buy again.
Oh and autoanything was great as well!" —Seth H from Manchester, NH bought an aFe Cold Air Intakes for a 2003 Toyota Tundra, 4.7L V8.
