Where to buy ProM 77mm MAF??

Thanks i just bought a 80mm from coolblueperformance for 239.99. Best deal i found. Hopefully this stops my stuttering problem. They mechanic said the maf is messed up. Wouldnt it throw code though???
 
Buy a Pro-M 80, they are cheaper and easier to find. It will flow a smibbage more and retract the heat a little better. The 77's are awesome though. You find a shorty version used for a decent price dive on it.
