New To Jet Products

Reviewed By Ken S (Verona, KY) Reviewed for a 1999 Jeep Wrangler —1/2/2009 11:44 AM

This Is My First Purchase Of Any Jet Merchandise. Easy Install....Well.....Except Changing Out The Stock Thermostat To A 180 Degree One, Which Is Required For The Stage II Module On The 4.0 Straight 6 Engine. That Seemed To Become A Major Ordeal For Some Reason. We Will Call That "SGS" ("S"tupid "G"uy "S"yndrome). All That Aside, Everything Went Fine. I Started The Vehicle Up After Install And After Warming Up For A Few Minutes, Immediately, I Noticed A Definite Smoother Idle. I Also Noticed A Definite Cooler Operating Temp On The Dash Gauge. After Driving Fairly Conservative For About 8-10 Miles, I Did Some Harder Accelerating From Stops And On Entrance Ramps To The Interstate. They Was A Definite Improvement In Acceleration Thru The Whole Powerband And The Throttle Seems Much Snappier. Now, Don't Read Into This Too Much. This Is Not A Mind Boggling Change In Performance, But It Is Noticeable. I Have The Banks Power Torque Tubes And Monster Exhaust And That Install Improved Performance. I Installed The Banks Power Ram Air System And That Improved Performance A Little. I Installed An Aftermarket Throttlebody Vortex Spacer And That Was The Least Noticeable In Performance. I May Try The Jet Throttlebody Spacer To See If That Is Better. Soooo...........What I Am Saying Is Every Little Enhancement Helped The Performance. It's Too Early To Tell About Gas Mileage. I Recommend These Type Of "Bolt On" Upgrades Over Tearing An Engine Apart, Changing Heads, Pistons, Cams.......Etc. I Purchased This Jeep New 10 Years Ago And Kinda Babied It Over That Time. I Also Installed New Fender Flares And Body Armor Just As A 10 Year Birthday Gift To The Jeep As With All The Above Installed Items.

in my opinion it's one of the best things you can do to open up your performance in your vehicle once you've done the Exhaust upgrades and cold air intake you can see a big boost in performance I can even sure from now and all 5 gears
