Is 91 octane high enough to burn with an 85mm C&L MAF.....

without any detination or drivability problems? 91 octane is as premium as it gets here in southern cali!

I never heard of a mass air unit requiring higher octane. Its when you change compression, advance timing, add blower.. that you new higher octane. Make sure your maf is calibrated for the injectors you have(stock I'm assuming). If you post your tech questions in the "Mod Madness" section you will get replies from guys with more experience with the 4.6 cars (96- to present).

Our cars run 10 times better with high octane then low test gas. The C&L maf uses your factory meter electronics but the real key in the C&L is the venturi shape of it . This speeds up intake air and also gets rid of the center post in the factory maf. Like I said before I could tell a difference in my car after I put on the C&L. DON'T waste money on a cold air intake, they look nice but don't do **** for performance. Plus if you go with a C&L you wouldn't be able to use the fender well end of the cai. I've got a BBK cai sitting in a box at the house. I could tell a difference with the new maf thats why it's still on the car. I did use the intake tube for a while though with the C&L, it looked good with the alum. maf, but my strut tower brace precluded me from using it so now all the BBK cai kit is in the box. TIMING ADJUSTER!!!!! I can set mine at 13* now, definite sotp feel. This will require you to run 91 or better octane, we have 93 oct. here in Illinois

Dude don't waste your money on a f****** cold air kit they are a joke before you put like 150.00 or what ever they cost into one, look at old posts on the site about cold air kits they're a rip-off. Put that 150.00 towards something useful like a T/A or different maf. If you get the cai kit get some nos stickers for your window, because those stickers will add about the same amount of hp as a cai kit. Well do whatever I guess it's your money. If your car is your main source of transportation go 3.73's, that way you won't be at redline on the interstate, well 3500rpmish. Thats got to get into the fuel economy.
