The JLT 3.7 CAI is a great bang for your buck !!!
Pro's: Price, easy install, no tune required (but recommended), big quality SandB filter (IMHO the best in the business) , great sound during normal driving (growl) and spirited driving (howl), great looks, direct straight path for air flow (no curves), JLT documented HP gains of 10-15 HP (even without a tune), decent instructions, quality packaging, 50 State Legal (includes CARB# sticker), durable quality intake tube and heat shield material, includes large area heat shield that allows fresh air from factory cold air scoop.
Con's: I had a little trouble with threading one of the MAF sensor screws due to excess plastic covering the mounting location. No biggie, just used a small screw driver to scrape the plastic out of the way. I also had difficulty properly mounting the included weather stripping around the hole in heat shield. I just kept it off like most people that have installed this kit. Make sure you properly center the intake tube in the heat shield hole or the tube will "rap" against the shield during full throttle. Having the weather stripping in place would probably solve this problem by "cushioning" the tube from contact. Maybe a different type of weather stripping could be used? Lastly, some may not like the drilling required for the "automatic equipped" install. However, the included instructions are "spot on" and not complicated. As long as you follow the directions and take your time, drilling a 1/2 inch hole is really simple in the grand scheme of things. Just make sure you clean out all the plastic shavings before buttoning up the install.
Overall this is a great mod for the price. Sure there are better quality (and more expensive) intakes out there but JLT has made a great intake for a great price. Personally, I'm glad I didn't go the expensive route. 10-15 HP without a tune is nothing to sneeze at.
I highly recommend this product.
