Hey guys, bought a g35 coupe the other day and loving it, noticed today that one of the tire stem caps is missing. I remember reading a post that said to only buy the oem stem caps because after market ones screw up the tire monitoring system/sensor.

Is that a myth and I can just go to autozone and buy 4 matching stem caps for 5 dollars or should I go to dealership and buy 1 stem cap for 7.50?

 

I've had aftermarket caps on for about 3 years. No probs.

 

Myth.... and a ridiculous one at that. The tire pressure is monitored with a sensor at the base of the stem. Anything beyond the end of the valve is irrelevant to the tire pressure reading. It would work fine without a cap on at all, but that's not recommended since it keeps debris out of there and the sun/UV from wearing on the inside of the stem/valve.

 

Welcome to G35 Driver RO55! Hurry to Autozone it's a myth, caps have nothing to do with how the sensors work inside your tire! Again welcome and enjoy the ride...Gary

 

Thanks for all the replies, will be at autozone buying tire stem caps tomorrow!

 

Make sure to get the 8-*****, the dice or the cobra heads.

 

that is a total myth man my car doesn't have tpms personally but I've put aftermarket caps on tpms cars with no problems at all.

 

But it totally throws off handling if you don't use OEM... So much harder to drift that way.

 

It's the aerodynamics.

 

Aftermarket caps gave me 2HP gain.

 

Welcome to the forum! Remove all caps and save weight yo!

 

I ****in knew some one would say this **** xD!

 

Lol

 

Axle weight!

 

I heard they would throw your wheel balance off...
