what happen if...?

I've just bought a C&L kit(tube,filter ,sheild,maf) off ebay, very cheap, for my gt 1996,the only thing is, the MAF is 85mm,so,i was wondering if the MAF is to big?

Should i install the kit without the MAF? and buy an adapter to intall the stock MAF?

So far i have these mod: PI cams
PI intake
75MM DRAGON T/B+PLENUM
U/D pulleys
timing pulley
screaming demon coils
O/R pro chamber+dynomax turbo mufflers
180 thermostat

future mod: 3.73 gear

I was just looking for a CAI,but the MAF was in the kit so i don't care if i can use it! however, i will install the MAF just to see if i can see a difference.
