so i went to my local auto parts store to pick up a set of champion truck plugs #4436 for my 99 ram 318 and they didnt have any so i said order me some, ended up they could'nt find any and called champion them self they were told that they discontinued the 4436 plugs and were not replaced with a different part or number, I guess i will have to go with a different plug ...

 

I looked two years ago last time i did a tuneup and napa told me the same thing. I just replaced with the coper champions.

 

car quest had to order mine. i ran them for 500-1000 miles and replaced them with something else because they weren't as good as my bosch platinum +4 plugs.
they're still sitting in my rolling toolbox in the shed.

 

i got champions from the dealer...copper ones for 28 bucks for all 8, and they work great IMO, same power as the E3's i had

 

i ended up getting the champion copper ones had to change them just seafoamed the truck and fouled a few btw i did a before and after compression test with the seafoam i gained about 20 psi across the board after the seafoam and i had 2 real low cylinders both 70 psi one is now 90 and the other is 150 im thinking there was a lot of gunk on the valves maby ill run more through to see if i cant get that other low cylinder higher???

 

wait abut 3K before you do it again IMO

 

I just got the regular Champion Copper Core RC12LC4s from Advance Auto for $15.

 

I had no problem getting mine when I bought them a few weeks ago..They had bunches of them in stock. Who knows.

 

I got the champion Platinums no problem just the other day.

 

I heard (I forget where) that the +4's make our engines ping.How do you like them?
