I have never installed a grounding kit on a Lexus however I have installed them on my previous acura and honda vehicles.

With Honda you do notice a very slight difference at low RPMs especially when the A/C is on as the displacement is small.

Having said that, I dont think I would spend the money on a ground kit again. Part of me still believes that maybe I wanted to feel a difference?

 

While there are aftermarket parts for cars that won't help performance, there are aftermarket parts that do.

The stock wheels are adequate. Lighter, forged wheels will improve performance. Why didn't Lexus put them on in the first place? $$$.

 

There must be a forum glitch.

 

hahahaha..... don't waste your money and time on it.

 

Come on, they must work - major auto manufacturers don't really know how to adequately ground their cars!!!!!!!!!

 

I did put a set of grounding kits and a stabilizer on my IS... I am not sure are they doing any work at all...?

 

You must be kidding! What gave you that idea?????

 

Your stock spark plugs are already Denso Iridium plugs. Check page 374 of your owner's manual.

Have you guy's opened up your voltage stabilizers before? I opened up my Apexi one and all it does is send the 12V+ to a filter capacitor, then looped back out. I just bought mine because I thought it looked cool especially at night with the glowing red Apexi name/logo Other than that I woudn't have bought it.

 

I did buy it a few months ago, but have yet to install it. Attempted to, but I couldn't even get to the first bolt, certainly not with my tools. Someday I will take it to a shop to install.
