Just out of curiosity, the headers I found in Hedman were only listed for the Buick engine, but even though the engine are the same is there any fitment issues with these? Do they clear the steering rack, the firewall,, etc.

Thanks!

 

just worked on one with headers, the thing was a total dog

 

One thing about headers you need to realize is that headers by them selves don't do alot, you need to add a cam/lifters and head work so you can increase the air flow thru the engine thus generating the power you want.

 

right on Disco Mike

 

Summit has them now for $163.95, but they are listed for the 3.5l. What about the 4.0l like in my 99' Disco I, is there a part number for it?

Anyone know where I can buy headers for a DI?

Never tried em. Look allright.

 

Have these on one of mine. great fit, same knock sensor issue as mentioned before, but a d2 sensor corrects. He also includes all mounting hardware, and bungs for the o2 sensors are already in.

Would recommend.

 

Genie tri-y headers on my Aussie spec D2 4L. Major difference in low end torque and mid range power. Much more pleasant to drive and holds gears longer going up long hills. Better mileage too which is always a bonus. Also put some high flow Magnaflow cats and a good mildsteel 2.5" straight through system with a resonator to kill any drone on the highway.
