"The heat is now dispersed well and the engine is much cooler.

Thanks for making a top quality product that REALLY works!" M.D. - Conn.
"The Size Large Louvers look good on my Wrangler -- but the best thing is they work well, too!" Justin F. - Mass.

Jeep is a '97, stretched frame, 41" IROKS, Dana 60 axles, Atlas Transfer, Chevy 5.7 V8...I could feel the heat from the vent coming out, and the hood was not hot to the touch anymore." T.W. - Ga.


"The 304 [in the Jeep] puts out a lot of heat and this is a great looking way to get rid of that heat." www.certifiablejeep.com


"We like these vents because they are easy to install and they come powder-coated with clean-looking stainless steel pop-rivet fasteners." Four Wheeler Magazine

"I am locating your hood louvers so that one is directly above the expensive ABS unit on my BMW. In Germany and Canada, where it is cooler, they don't replace these very often. In the heat of Georgia, I have gone through two in four years -- it must be the heat. It is directly above the exhaust manifold. Your hood louvers should solve the problem." - Roger G., Georgia

"The louvers are awesome!!!!!" - NBPDP Racing
"I installed the louvers on Tuesday, drove over to Moab, picked up some new tires on Thursday, followed a group of Goodyear tire testing vehicles through Pritchett Canyon on Friday, and returned home on Saturday. The louvers worked! Thank you so much." - Jim B., Ariz.
"I have some plastic hood louvers now -- what a pain! Once or twice each year I have to take them off and repaint them -- the paint is always flaking off, and that's after using special plastic paint! I'm ordering your powder-coated aluminum ones because I'm tired of messing around!" - Jeep Owner
"Ambient temp is 117° on average these days, and having a black Tahoe is a death wish. The A/C has never been so cool even after idling in the sun for an hour." - Manaf H., Kuwait

"I did a V-8 conversion on my Jeep, but it ran too hot. As soon as I put your hood louvers on, it immediately solved the problem." - Paul L., Minn.

"Just overheated the all-aluminum engine of my Land Rover -- $2,000 to repair warped heads! Putting a set of RunCool Hood Louvers on this weekend -- would have prevented this!" - Bob B.
"Great results -- temp gauge (engine) went down 23 degrees. Now on a 100 degree day with air conditioning running, I don't get worried anymore about overheating."
- Ken G., Jeep Cherokee, Colo.

"South Florida gets very hot during the summer and stays that way for most of the year. Keeping our K-9 partners healthy and safe is very important to us. We have used hood louvers since 2002. We just swapped out our old 2002 CVPI vehicle with close to 8000 hours of city driving and idle time on the original engine. When we participate in joint agency training exercises we are the only ones to have our hoods closed. We found that hood louvers keep our vehicles running cooler by dissipating idle heat like no other method we have found." - Naples, Fla. P.D.

"They are perfect...Thank you!" - Steve G., Las Vegas
"My new Jeep Wrangler JK with automatic transmission overheats when I take it off-roading. I installed your hood louvers and they helped A LOT! - O.F., Calif.
"Got the louvers last night, very nice quality. I know good metal work, and these look real good." - Steve H.
"Anything you can do to reduce heat...will make the truck last much longer."
- Diesel Power
"I noticed the difference on my temp gauge right away -- and I like the looks of them!" - Rodney P., New Mexico
"Yep they keep it cool. I have a transmission cooler mounted right under one, with a fan blowing up through it." - Bottoms Up Rock Racing
"It's a GTP and yes it's supercharged. I love speed. It already runs cooler than normal, and it is just the middle of April!" - Silvia K., Canada
"Got the louvers today and I must say that they are everything I was hoping they would be...great job!" - Eric H., Oregon
"It's amazing the difference they make! Even the passenger compartment is cooler! Before your hood louvers, some sensitive electronic components under the hood got so hot my gas mileage dropped 5-7 mpg (but the engine ran fine -- so I didn't discover this at first). I've run your hood louvers for 3 years, and that hasn't happened since! Now I'm ordering another set for my truck, and I'll soon order a set for my other Jeep." - Robert C. Missouri (Jeep Cherokee)
"Friend did IR thermometer test on intake...on intake (using your louvers) he hasn"t seen the temp go above 130 degrees -- previously was over 150 degrees." - O.F., Calif.
"Got the louvers last night, very nice quality. I know good metal work, and these look real good." - Steve H.
"Instead of spending $600 or more for an intercooler, I went for giving the RunCool Hood Louvers a try and can honestly say that they more than let the expectations I had for them...Lowering the intake temperature has made a big difference in power output, A.C. efficiency, and my peace of mind...and have had numerous comments about how good they look." - W.D., Texas

"I've owned Jeep Wranglers before, and I am now looking around at used ones. On nearly all of them, you can tell that much of the hood paint's clearcoat had popped right off because they run so hot!" Toby K., Dela.

"They really get HUGE heat out of my diesel!! I'm impressed so much I just can't stand it!!!" - Ted R., Granite Falls, Wash.

NOTE: The fasteners shown here are screws, not the Stainless Steel pop rivets (which are smaller).

Air flow through and out of the hot engine compartment is what these real hood louvers are about!

Note the air flow, as seen by the movement of the tissue paper. This is due to a combination of rising heat and the forced air flow by the engine cooling fan (at 1500 rpms). The “ram air” effect of the air being forced through the engine compartment and out of the louvers, as the vehicle moves forward, would add to the air flow through the louvers.

The RunCool Hood Louvers here are mounted on RunCool's president's Jaguar XJS with a full-house Chevy 406 small block.
