Greetings all! Registered newbie but have spent time searching threads and have learned a lot. Thanks. I hope to tie into everyone's experience and vision. Suburban Air Intake issue Vehicle: 1993 Chevrolet K1500 Silverado Suburban w/5.7L, TBI and has/had a thermostatic air cleaner with heat riser (mechanical wax pellet design) no sensors or connection (at least visible) to ECU (ODB1). Application: AEM Brute Force Intake Model # 21-8001DP (w/ throttle body spacer) to above vehicle. I am considering purchasing and installing this unit in the near future. But there is one potential “showstopper” that still remains unresolved. AEM did not offer a lot of consolation or have any “specific” information. All my instincts tell me that I only have something to gain and little to lose. However, I prefer to be cautious when spending any hard earned cash, especially now a days. It is my hope, that you are able to provide some clarity to this issue so that I may proceed with the purchase and installation with minimal trepidation. On the AEM website description of the product for the respective 1993 Suburban application, the following caveat is noted: “* Excludes models with thermostatic air cleaners (heat risers).” This left me with a lot of questions so... My inquiry is as follows: Why is it excluded? What is the issue (or issues) with thermostatic air cleaner models? (Is this just AEM self-protecting from the “legalities” that surround the alteration to stock OE emissions systems thus not encouraging people to break emissions laws?) PERFORMANCE: Are there any other liabilities than potential extended choke time? FITMENT: Will it fit? (I have poured over the installation instructions and can see no impasse to successful installation if the heat riser is capped off.) ADVICE: Has anyone used this or an equiv. intake?; Experience with AEM? Suggest a better product? Share experiences? Intake assets/liabilities? I thank you for you time and effort in advance!
