Hey new guy here...1999 7.3 td crew cab. Just finished 5" magna flow installation. My question is any performance data for AFE vs quadzilla cold air intakes?

Or user experience?

Thanx

 

i have an afe and like it alot no problems.most of the intake that are reuseable are good. chris

 

Welcone to FTE.

I don't know about the quadzilla, but I have the afe stage II, it's a supreme filter system, but costs alot. Many her use the 6637 with great success much cheaper, do a search here for the kwik 6637 filter mod.

 

welcome to FTE ...if you have the early 99 most likely the quadzilla will not work unless you get extra parts and modify your intake tube..by that time you might just as well do the 6637 mod...im sure the AFE II and the 6637 flow alot more are then the quadzilla as well...

 

AFE Stage II with a Pro Dry S filter here.

No problems at all. A little pricey though.

 

Thank you......you wern't kiddin about the price(afe 2 stage). But I do love this truck, manufacture date 3/98.

Just gettin started with the performance upgrades so any info you all have is greatly appreciated

Brian

 

Without a doubt the best bang for your buck is the 6637 Airfilter.

 

you have the early 99..my build date is the same as yours..you have 3 choices..6637,AFE II or the AIS...if you would like to see the diff's in the turbo for the early 99 and the 99.5-03 trucks..click the exploded view link in my sig..

 

save your money for the DP lol, buy the 6637, is the only way to go.

 

I just finished replacing all 4 door actuators and the exhasust....I will check out the 6637 this weekend and get back to you...

A friend has a dyno source 3 position chip in a o2 7.3 td and i'll I got to say is WOW....

 

that means you will chitting your pants when you put in the DP tuner... you will be walking all over your friend just in the 80 econo every time you race...

 

I have a AFE stage one that I am selling...

Let me know if that siomething that you might want... I am doing the 6637 mod..

Doc.

 

Thanx for the offer but I ordered two 6637's today with the rest of my filters from the filter web site found here...........local parts store wanted $67.00, on-line $22.37

Just happen to have some 4" EMT pipe at the shop if I need a extension

this is a great site and i really appreciate it

Ron, I will get back to you in the future about the DP Tuner.....it's gonna happen
