Changed the plugs.

Re: Changed the plugs.

It think tubulars are a great mod... IF you get them cheap which you can... I would take them over a $300 set of headers anyday.


There were threads about dyno results, only like a 3-5 hp difference, and a good $250-270 difference in price.

Never done them on the 3.8 but the 3.4 is a breeze. My LT1 is a biiiiotch to change. Remember kids, when replacing plug wires on a 100k+ mile opti crap to change the opti crap too.

Heat shields and log manifolds are a PITA to deal with. If the heat shields are off, its 10x easier. But with headers, I can do it in 10 minutes. With the logs....almost 1 1/2 everytime.

both my cars have stock manifolds WITH heat shields and emissions tubes

Re: Changed the plugs.

Getting the heat shields off the logs was probably the hardest part of doing the tubular swap. Took way too long and I eventually resorted to cutting the heck out of them.
