ok so i have a sputter at a leveled off speed and i was checking my plugs today..

here is the problem, when i pulled out the exhaust side plugs i found BOSCH IRIDIUM plugs!!!!! this truck only has about 28000 on it i bought it with 24000 why would it have Bosch in it? the dodge dealer says they NEVER use Bosch plugs... so im at a total loss, this plug doesnt say anything on the porcelain but bosch iridium and thats it, there is a number stamped into the metal FR8T1332
thats all there is, the local Dodge dealer says they dont build dodge trucks with Bosch plugs any body been through this? any help???


thanks

 

Factory OEM plugs in the 2008-2009 4.7L with 16 plugs is Bosch coppers in the top and Bosch Iridium in the bottom. Top plugs changed every 30k and bottoms changed every 100k.

 

hi, how do i tell if the bottom plugs are the right ones? there is just that stamped number on the base and the dodge dealer says they dont use bosch thanks

 

Your dealer is incorrect.

Intake: Mopar part# SPFR8TE2AA is a Bosch part# FR8LCX+ and would be replaced with Bosch stock# 7962.
Exhaust: Mopar part# SPFR8T1332 is a Bosch part# FGR8LQI0 and would be replaced with Bosch stock# 4508

Request those part numbers at the dealership, or those stock numbers at an auto parts store. If you want to verify, call Bosch and they will verify those are the OEM replacement parts.

 

Brandon Thanks... i did call Bosch and they did tell me that they produce plugs for "factory direct use" and thats why there isnt a number stamped on the top of the plug...


as for the dodge dealer here in town this isnt the only time they were talking out there *** they wanted to charge me like 140.00 to "wire in" a brake controller plug under my dash, when there was already one there, thanks to yall here i found the plug myself

thanks again

I hate seeing people getting hosed by the tards at the stealership.

 

Say it ain't so!

 

I am glad I found this thread.
Went to my local advance auto to get plugs and they couldn't cross the numbers for my plugs. We looked up champion, NGK, denso, etc. Didn't think of looking at bosch.
I was set on getting Champions. I was about to break down and go to the dealer.
It seems that the 4.7 with 16 plugs really throws people off including the dealer.

 

do you think it would be safe to follow the same with my 05 hemi. Iridiums in the bottom and coppers in the top

 

Your Hemi needs 16 copper plugs.
