PPE Header Issue Discussion
Hey everyone,
I just ordered set of PPE headers from Figs this week, and I started doing some more in depth research into some of the problems people on here have been having. One thing I have noticed however, is a number of threads that don't seem to ever get updated with solutions to the original stated problem.
I know a majority of problems seem to revolve around the O2 conditioner, or the wiring thereof, and the upstream O2 sensors. I notice though a lot of people were seemingly getting CELs, having them reset, only to have them come back again. Is this commonplace? Those that have had issues with CELs, were you able to get them fixed and not return?
I guess I am looking for some piece of mind in that what I purchased and plan on installing shortly, will work like I want it to. I know there are many other new PPE owners coming on through Figs PPE sale, I am sure they would appreciate the info as well.
Thanks in advance to anyone that replies!

cant wait until mine come in. should be any day now.
is the entire wiring on the conditioner done under the engine bay? i called PPE but they were busy the past couple of times but they were nice polite guys.
i think im just going to install these myself. the instruction looks easy and after dropping the subframe, looks like a breeze.

The electrical conection its not that hard , read the instructions first and if you have any doubts on wiring colors call them up their custmer service is far from none, i got a cel after installation we scaned the ecu and the problem was on the primary o2 sensors wich they have nothing to do w the conditioner, the conditioner is only for the secondary o2 sensors this are the ones that sense the absence of the cat converter on the header the primaries are for the air ratio and they from factory come before the first cats wich are removed w the headers , but i recomend you buy a set of o2 sensors because they are brittle and during removal they tend to get damaged dont buy them at the dealer too expensive they are made by denso and if you look them up you will find them cheap the primary o2 denso part # is 234-9048 you can find them in amazon for arround $75 to $115 vs dealer price $235 pluss for the same thing the secondaries if you get them out find your in good luck bit if you strip them the denso part no is 234-4521 i think this is al you will extra need for your installation trouble free, the instructions sucks at least on mine wich was the old style that had to replace the dip stick and the part is a pain in the butt other than that the conditioner installation is simple once you know what to do and the plugs you need to interface, the mechanical installation if you are very mechanically oriented and have acces to a lift and some jacks you can doit in arround 6 to 8 hrs , i did mine in 10 hrs because i spended two hours trying to figure out the dip stick story and 1 hr trying to figure out the instructions, what i did is that i downloaded the instructions from sikky and the ones on the ppe kit use them both and then got the whole picture , but both instruction set sucks sikkys is slighly better

95 percent of people with PPE header problems either screwed up an O2 sensor or installed the O2 simulator incorrectly. That was pretty easy to do seeing as the original wiring instructions that came with the headers were wrong. That was corrected some time ago. I payed 1000 bucks to have my headers installed but they were done right the first time with no CEL's at all. You screw up one sensor and your out 200 bucks so I just dont understand why people insist on these 5-6 hundred dollar header jobs. You get what you pay for.. Im sure 150 bucks of that went to installing the original (ridiculous) dip stick...

My headers where brand new but i bought them at a reasonable price to a guy here in pr that bought them when they first came out and never install them , the new ones dont need to deal w the dip stick, those did!!!
No matter what you pay on the installation the issue of the o2 sensor going bad after removal is a matter of luck they are just too brittle...

$800 to $1000 is about right what a reputable shop should charge you for the installation other than that its a rip off and trust me even thought paying that amount of money for the installation does not assure you , your o2 will survive the removal and installation

buying two new o2 air fuel sensors is such cheap insurance, i dont know why it should bother a lot of you. even if you can take off your old ones, why not just put new ones in for assurance down the road for even longer reliability? advance auto now sells denso sensors and with their online discounts, they are like 140 a piece.
