The less restrictive air flow of a modified intake in combination with less restrictive exhaust has provided a fantastic improvement in overall performance (plus it sounds great) for my titan. Here's a previous thread if anyone is interested in saving some $$$. Also, a drop-in K&N panel filter hasn't caused me any MAF sensor issues. No problems 35K miles later, except for some disgruntled hemi drivers in my area!!

This intake system is waterproof & only uses ambient temp air. PM me with ant questions.
