I finally found a PI intake for a price I was willing to pay - 20$ from the local pick n pull. :D There was a row of 3 1998 crown vic police cars and one of them happen to have a PI intake. The others of course were NPI like they are suppose to be. I've been watching for a long time, but I'm always too slow and it is long gone or the intake is still there because someone took a hammer to the plastic. :rolleyes:

Anyway, there was a foam glove covering on the bottom half of the intake. It looked like it protects the intake from the heat of the engine valley. Anyone seen one before? Recommend for or against using it? I was thinking I would keep it because it could potentially reduce the temperature of the intake and thus the intake charge. I am thinking most people don't have one though?

Next, I grabbed the coolant line and it just has a flare on the end. Do I have a nipple on my 97 block and I can just replace the O-rings and push it together? Unfortunately, I didn't think to grab the alternator bracket. I think it was long gone anyway. Can mine by re-drilled or is it a completely different shape?
 
If both your NPI intake and the new PI intake already have the aluminum crossover, you can just switch the crossover from the old NPI intake to the new PI intake. Then you don't have to invest in a new alternator bracket, modify the existing one, or drill/tap the extra coolant sensor.
 
Yup, both the PI intake and my current NPI have the aluminum crossover. Looks like it is just bolted on with 6 bolts. That would be slick. :D

Go get that 13 second pass, B.

Can't answer your other questions. The last time that I did this swap was 4 years ago on my 97gt. I just remember not correctly drilling one of the coolant sensors. Car still gained .2 and 1.75ish mph in the 1/8 mile with similar 60 ft's and DA's with the fans running full time.

Since the last time I went to the track, I add PI cams, a drop in K&N and underdrive pulleys. I was thinking it would nearly run a 13 already. Seems I have quite a list of modifications now. haha. I hope the PI intake makes more difference than the PI cams. With the PI cams, I only noticed it was more willing to rev another couple hundred rpm, but may have just been making noise instead of power up there.

So if I went to the track, I would throw the tweecer on (I made a tune earlier), swap on the nittos from the 88 and these other modifications. Should be good for a 13 in nearly any weather. :D


:pics: please

Sure thing. It is a ford part: 2W7E-6N041-AA C227C Cavity #2
Has anyone seen or heard of one before? I think I'll try it, because it won't hurt anything except the 5 lbs of weight it adds.

ALL police and hd fleet ford vehicles has them, i did my pi engine swap in my 97. the engine was an 05 interceptor motor, it to had the foam piece. i kept mine just because it does make a difference and keeps it from heat soaking, some say its a myth but...it does make a difference.
