I did the Autozone $70 DIY kit... i recommend staying away from 90 degree elbows, i plan on replacing the 90 with a coulple 60's to make the air flow less turbeulant. I am satisfied with all but the 90 deg elbow. I would recommend trying it out.

 

i have one like this one except mine is for a V6 but they are similar

i think its better quality than the one you originally listed and plus it comes with a K&N air filter. no 90 degree either
