My butt-dyno was telling me there was a power difference but I didn't want to get ahead of myself. On Friday I installed my K&N FIPK Kit and did a Mobil 1 Synthetic oil change (to change out my oil that had the seafoam in it). It rained all weekend so I hadn't gotten the chance to test the change. The results I got today were incredible.

The numbers:
16.45 @ 84.8 MPH
16.52 @ 84.5 MPH
16.53 @ 83.9 MPH
16.45 @ 84.9 MPH
16.59 @ 82.8 MPH

Avg with stdev: 16.51 sec +- 0.06

This is a 0.68 second average improvement on my 1/4 mile time. Not only that, but the times got even MORE consistent than after I did the seafoam.

I am very pleased with this intake...

 

Glad you like the kit.

How many miles did you put on the odometer with seafoam in the oil before you changed it? Did you change the filter too?

 

I wasn't keeping exact track of it, but I would estimate around 150 miles. I changed the filter to an AC Delco. I also forgot to mention that I cleaned the MAF sensor while I had it all apart, so that probably contributed to the time as well...

 

Ok, I should check my mass airflow sensor. I oiled the heck out of my cone filter before the winter.

 

yeah I just bought some of that quick dry electronic parts cleaner at AutoZone...

 

Your FIPK 2 will work even better if you install a flowmaster, gibson or any type of muffler...now that the engine is inhaling good, it needs exhaling...after I got the custom y-pipe the truck woke up one me as if it was dead before...

 

I got a Dynomax catback in the mail so hopefully that does the trick

For the y-pipe, did you have to actually have it custom made? Like, at a muffler shop or something?

 

You have to have it custom made @ a muffler shop...this made my truck gain the low end I lost after I installed the muffler...my 4.3 now sounds like a 5.3!

 

What diameter piping?

 

Can't remember the exact diameter... I believe it was 2-3/4"...go quote it at your local muffler shop and they'll help you out on that...
