Hood louver different hood cut ideas

[Tj04]

I'm thinking of not doing a traditional hood cut method for the Poison spider hood louver.

I was planning on doing a series of 2.5 inch holes or something instead of one big cut out on each side. The purpose being I could plug the holes with rubber plugs during winter. On city buses here in MN they plug the hood louvers in winter and I found it interesting and would like to do the same.

Any other ideas/opinions on cuts?
And what kind of rubber plugs would fit the hood and stay?

I was thinking of using these.

This is what I was thinking except doing a few less holes.

That looks pretty horrible. You might be better served to get a set of Genright louvers, (see my pic at left), mount them with anchor nuts and replace them with blank panels when it gets cold.

X2 to this.

I mean you don't really need to louver at all, unless you have an engine other than stock.

Plugging the hood louvers won't do the same thing for you, as it does for the city buses. I'm 99% sure that those louvers are related to the actual temperature control system of the bus, so by plugging them off, the engine reaches operating temp more quickly. They are most likely diesel, so temp is way more important that on a gasoline engine. Its the same as blocking the radiator on front engine bus or Semi.

The hood louvers on a wrangler are all for looks. They will only reduce underhood heat (which isn't necessary) and won't affect the operating temperature of the engine itself. You still have a 190 degree thermostat, and the engine is still going to run at 210 Degrees. If you want it to heat up faster in Minnesota, get a block heater installed or put a canvas windscreen in front of the grill...(I'm not recommending that though...block heater would be WAY more safer)

The louvers on my Jeep help keep underhood temps down, and lets a lot of hot air out when I shut it off. I was having Heatsoak issues until I did that. Of course, that was about a week BEFORE I heard about the insulation trick.:hmmm: But it still works.

Yup...that is what I said they would do. OP was talking about blocking them off to heat the engine coolant faster, I believe.
