GP Thunder 8500K H8 Install Hell...

Sick Speed · 07-19-2008, 01:54 AM

Just installed my GP Thunder 8500K. Very pleased with the results daytime and nighttime.

However...this turned out to be a PIA install. What should have been less than 5 minutes...turned into 45 minutes.

My right side OEM H8 came out with a simple turn and I installed the GP Thunder within 1 minute. No problem.

Went to the left side...popped the cover off...went to turn the OEM H8 and it felt jammed so I had to forceably unscrew it.

Went to install the GP Thunder and for the next 40 minutes I could not get the freakin' GP Thunder to match up with the housing. I thought it was just because I had larger hands and had to work it in with two fingers (no jokes here).

After enough time had passed I unhooked the GP Thunder from the wire harness and compared it to the OEM bulb.

Sure enough...one of the metal supports on the GP Thunder was larger than the OEM and this was the reason it would not seat.

So I pulled out the metal snips and trimmed at least 1/8 off. Went back to seat it...wouldn't fit. Pulled it again...trimmed another 1/16 off...this time it fit.

Anyone else have an issue seating their GP Thunders?

Definitely a sounds like a defect, sucks about aftermarket sometimes.

Mine went straight in in under 2 minutes (sorry)

gp thunders should take less than 4 minutes for install, before and after pics please?

simp0man · 07-19-2008, 01:06 PM

Yes, before and after is nice. I don't have that brand but I am happy with mines.

under 4 minutes? wow...
took me good 30 minutes because these OEM suckers were like glued on and area were just too tight and narrow...

ya i've heard a lot of different stories about fitment issues...that's why i'm so hesitant in getting them...

jeanchristophele · 07-20-2008, 08:18 PM

Hello I also took long on the left side, just gotta be persistent with it and I didn't trim anything. Finally after 15 minutes and alot of sweat I managed to force it in 3 o'clock.. during the process it felt like I was going to break something but I just applied enough force and it locked in. So yeah only the left side you gotta be patient with I dont think the bulbs are defective in anyway

i2iSTUDIOS · 07-20-2008, 08:19 PM

is there a diy for the changeout that you can link me to? The ones that I have seen mean I have to remove a million screws like when I replaced the D1s thanks.

Vacek · 07-20-2008, 09:05 PM

2 minutes per side here .... piece of cake.

Sounds like you had a bumb bulb.

Rafstar · 07-20-2008, 09:41 PM

exact same thing happen to me. I got the left side to fit. The right side wasn't going in and I didnt want to force it too much
