The Poison Spyder Hood Louver helps keep your engine running cool by promoting airflow through the engine compartment. Many factors can contribute to high under-hood temperatures, which can translate to higher engine coolant temperatures and overheating. Headers, slow speeds, flex fans, and the cramped spaces of the engine compartment can all contribute to increased heat and reduced airflow. This Hood Louver kit frees up airflow through the engine compartment, allowing hot air to escape and cooler air to be drawn in through the radiator, improving cooling of both the engine coolant and under-hood air. Rock-crawlers and slow-moving vehicles are especially susceptible, as slower speeds naturally result in reduced airflow. Poison Spyder Hood Louvers are crafted from quality, thick gauge aluminum sheet. They are CNC laser-cut and precision die-stamped. Aluminum makes the hood louver both light weight and corrosion resistant. But its thick enough to add some rigidity to the Jeeps notoriously thin sheet metal hood, helping to reduce "hood wobble" at speeds. Hood Louvers are fairly easy to install but do require some drilling and cutting of your hood. Stainless steel fasteners are supplied, as well as a full-size template with instructions for cutting the airflow holes in the hood.
It’s well made, packaged for shipping correctly and looks great in the anodized black as a contrast to your hood color. Oh and it does a fantastic job of getting the heat out from under the hood. It also fits really well on the Toyota FJ40 which is what we have installed it on. I’ve purchased quite a few things from these guys and they are on point every time !!
Great brand and I appreciate the continued availability for the TJ.

Q: Does this addition help with the 4.0 running cooler? Answer this question
A: It helps increase the air flow, especially on the trail. It does allow more dust into the engine compartment though.

A: Yes my tj runs around 10 degrees cooler, however it’s a mixed blessing it doesn’t want to come up to operating temperature in the snow.

A: I have a small block Chevy in my TJ so not comparing apples to apples but i can feel the difference between having it and not having just touching the hood it definitely worksÂ
