Just curious how many people use these? i took mine off cuz it just became such a pain in the *** to keep removing them if i wanted to get around the fender/take the front bumper off...

i dont care for them but i do think it increases cabin noise and theres always a **** ton of rocks getting kicked back by my r compounds.... just wondering who doesnt use them and if they notice increased noise levels?

 

i still use mine, but i trimmed a ton off each side because of tire rubbing. it keeps alot of the road debris out of the bay and behind the fender.

i just ziptie the front part of the liner, so i just snip and im able to access the front bumper mount, i take my bumper off alot though since its low, every oil change etc the bumper comes off.

 

There is a thread out there about using mesh instead of the plastic. This causes a low/hi (don't remember) pressure inside the engine bay and people were getting faster 60-100 mph times out of it. I'll see if i can find it.

Edit: found that quick

Huh? Where? I think the mesh works but I have never seen anything conclusive.

 

It's in the link, after reading the link there is a lot of speculation and not much conclusion.

 

Are you talking about the plastic fender liners inside the wheel well? If so keep them in there! The engine bay will get loaded with debris kicked up from the tires and the oil cooler(s) won't have proper venting.

 

If you drive in the rain, you will have a big mess with no fender liners.

 

My drivers side fender liner came off one day, and the following day I had to drive in the rain all day. There was actually no water that got into the engine bay, then again I avoided all the big puddles I could I would definitely keep the fender liners in there if you have them.

 

^^^^

I'm sure water got in, it just evaporated quickly from the heat/wind.

 

like most things automotive....I can't imagine getting that much of an increase in 60-100 time from mesh vs plastic.

 

His was 60-160 and only 1 way to find out.

 

true..but not about to take my fender liners to find out lol. I'll let you young guys figure that one out.

 

We have had multiple cars trailered to the shop with fried PFCs, that were all missing the driver's side fender liners. Cars all stopped running suddenly after driving in wet conditions. Can only figure water splashed up on the diagnostic boxes and shorted out the PFCs.

 

 

Yup, from someone who lives in Rainsville (AKA the UK), they are sort of needed! Wouldn't dream of running without them tbh.
It's my understanding that they also help significantly with cooling - seal the bay and maintain the area of low pressure inside it that encourages air to enter throught he heat exvchangers - i.e oil coolers, rad, IC.

It does bug me how there's a mssive gap in them at the front though, makes me want to get the arches tubbed...
