i just installed a volant Cai on my 05 truck, i was surprised at how loud it was in the cab are all Cai's like this

 

pretty much. do u hear the sucking noise a lot? how does the pickup feel?

 

how do you like the volant? im lookin into getting one but was told a CAI w/o a tuner will make the engin run too lean. does it sound the same as stock, but louder? i actually like the sound. closest thing to a diesel turbo windin up i can get. lol

 

i would check on the whole engine being lean thing for an 07 i thought that problem was for the 05-06 years. There is a deff difference from stock!!! the whole sucking noise has to be gotten use to it but it has improved my get up in the truck.

 

thats good. i was told that 07 shouldnt have a problem and i was also told it would or might. id hate to spend 400 and not be able to use it until i bought the $400 gryphon plus custom tune to run it... i like the sucking noise so it wont be too hard to get used to

 

I have a Volant and dont hear any noise at all but idk if its because of my exhaust but didnt really notice any new noises. But I like it alot, I installed it the same time as my tuner so idk what made a bigger a differance.

 

i have an 08 f150 but its a V6 and i have had my K&N cold air intake on for about 10 months and have had no problems. at first when you put it on, it may run lean, but your computer moniters every 500 miles you drive so after about 500mi, it should adjust itself. like my 04 f150 heritage i had. went from 18.9 stock for an average to 19.9 with a K&N drop in filter, to 22.5 with the intake(same one that is on my 08) but at first when you put it on, your computer knows it is getting a lot more air so it takes about 500 miles to adjust for it. i know the first tank i did got 25mpg average, the next one got 18, then the next was 22.5 which is where it stayed. computer leveled it out after a bit. my 77 series CAI from K&N came with a dyno printout of a similar truck. it had a 99 f150 V6 with 140k and it got an extra 6.15hp to the rear wheels. my 04 had 30k so it probably got more power than 6.15 out of it. and my 08 had maybe 2k on it when i installed it. i am up to 16k now with no problems.

 

actually i have heard that if you use a tuner without either a CAI or a higher flow exhaust, that it is bad for your truck. having one or the other is ok but both is best. i have the stock exhaust on mine but have my K&N intake. no tuner but no problems with my 08 V6 yet from the intake

 

It's only the 04-05 5.4L models that really run lean. Older models and trucks with any other engine shouldn't have any problems. Supposedly it was fixed for the most part in '06 but I still think it's better to be on the safe side and have custom tunes.
