I would like to add that I did a similar mod to my grand marquis ( 2000 4.6L) I noticed that when climbing hills on the interstate ( live in NC and travel to TN weekly) That I would loose speed with cruise set as much as 7 mph and the car would down shift really hard. Once I put it back like it was the deceleration would be 2 to 3 mph and would down shift quickly and smoothly. Mpg on interstate suffered as well- 2 mpg less some times but always atleast 1 mpg.
@mrrodneyalong I noticed about the same thing it seems the ECU can not correct for the extra air a chip would really help and that along with a dual exhaust are next on my list.
I Looked into adding a CAI for my 04 P71 and you can't get them in o4 they upgraded the air intake and Suspension and Steering to the Marauder if I Tried to mod the CAI in it wouldn't pass smog and would confuse the Computer sys have to go with a Drop in and opening up the Bottom of the airbox will throw it off also 04's and newer have Been Tweaked the Best Ford could do with a 4.6 if you Look at the new interceptors their 360 hp and sixes by ford amazing what they did
this is nice,,,put the k&n drop in in it ,,,,,i made the intake kit that afe sales with a spectra maf adapter and a 9in cone open ended 750cfm filter for $40 instead of $175,,,,i armaflexed the rade hose and mad a nice heat shield that droped my intake temp by 30 deg far ,,,,,,
it wont improve anything, the reason why the cone is vented to behind the bumper is so that only cooler air will get sucked thru your intake, if u cut the box, all the hotter engine air will enter ur intake therfore shittier performance.
I have an '05 Merc Grand Marquise. Though not the same, but is is to a certain extent. I think they have more pep than the Impala that I had did before but that is just me.
You took the air resonator out of the inner fender?? I did that to my Tbirds. It made the 4.6 a tad louder but not much. My 3.8 on the other hand it was like WOW you could really hear it sucking in!
Im speaking in theory/ im no engineer and know nothing about building car engines, but wouldnt the 4.6 get a bit better gas milage than the 5.0l and I bet those cvpi w/ the 5.8 & VV probably sucked gas. that corvette w/ the 7.0l can get 25 mpg and thats w/ my vic got yet it only has a small block 4.6
My old 302 had some torque with a CAI and open dual exhaust cut-off after cats. I also removed some weight like 100 pounds or so. Never had a problem kickin some honda ass on the streets of O'Fallon.
I own a 97 crown vic lx and althogh I wasnt interested in buying a new car I went to the mercury dealer and tested a 2008 model grand marquis and I noticed a major difference, it is much faster ,throttle responce, along w/ improved steering (probably because of the update rack and pinion) If I wanted to put r&p on my 97 is it worth it cause recirculating ball is less precise/ (it sucks!!)
I am wondering are you going to buy a kit or are you going to make it yourself? If doing it yourself are you going to use a K@N filter head? Could you upload vid for me cause I want a diffrent look under my hood.
if your going to do that to the airbox at least do it right. u should have left the top edge to the bottom half of the airbox so that the filter will seal properly. and get a K&N filter, that stock paper filter is too restrictive.
Ditto! I was actually thinking about doing something sorta like that to the 89 Crown Vic but I'm going to use a hose running from the box to under the bumper to scoop up the air.
You can convert the lopo to HO..But the best engine swap so far for the crown Vic's has got to be the explorer 5.0 HO they have a bit more torque and thats what crown Vic's really need is more torque.
And I actually prefer the older 5.0 becase there pretty easy to work on. Anyone here ever try to change a headgasket on a 4.6? Its a pain...Other then that its a pretty nice engine.
ever put a water pump, thermostat or even spark plugs on a 5 liter crown vic? what a pain in the ass. the 4.6 is so much easier to work on for most things. i'll give u the head gasket but how about trying to just replace all the vacume hoses on the 5.0 jesus u have to take the whole upper intake off and that in itself involves tons of bullshit. as far as the way they run, the 5.0 has a little more torque but the 4.6 more than makes up for this with strong mid-range and top end.
Yup....I grew up with the 5liter, It gets easier with time...lol...with the water pump I start out by removing the radiator....and then the belts...and so on....No too difficult after the 10-15th time:) Oh and the 5liter is pretty cheap to hot rod too:)....But I do like the 4.6 also dont get me wrong:)

@kininc Slight mostly just sound once I get cone filter and better intake of cool air will help more.

You should rev it up so we could hear the deeper sound.

you should put a k&n filter in not the round one were you have to change your filter set up theyll sell one that takes you old filters place.
