Can anyone tell me what the factory T/B size (mm) on a cobra intake is? Also looking to get some injectors and MAF if anyone knows of some used ones in good condition?

5speed GT

i believe its 65mm

Thats what I was thinking just wasn't sure. Are you runnin stock injectors with your 75 mm MAF?

5speed GT

yep sure am

edit: well, I'm running stock 1996 explorer injectors which are 19#(same as stock mustang) but they are the new deisgn which have a better spray pattern... but they are stock sized injectors

Is the pro-flo MAF adj. for variation in injector size,or did you purchase it for 19#"s?? sorry for all the questions,I'm doing an intake swap...

5speed GT

no problem... the pro-flow you order per injector size, so you cant change it later. I know the C&L has interchangable"tubes" so you can buy the unit and buy the different sampling tubes later for different injectors.

I went with this one because I dont "plan" on going with bigger injectors

I gotcha. Well I'm lookin at going to 300-350HP, when its said and done...Just not sure if the 19#'s will hold up. I took em out last night and there not in very good shape.I got the new O-rings and caps but Just skeptical on whether or not they're going to do the job , if you know what I mean.

5speed GT

300-350 def need to step up to 24#ers, i believe the 19s will be at 100% duty cycle when wide open

Thats Exactly what I was thinking. As a matter o fact I've been toggling back and forth from here to E-Bay, lookin. Trying to find a good deal on MAF/Inj...Im on page 32[&:]

I agree...19's are good to about 290-300rwhp. You'll need 24's after that.

Cobra stock TB was either 65mm or 67mm...... 65 I think....
