i have a 97 firebird lt1 i need to change the coil out what should i use go back with stock or after market

 

I went with stock, works fine.

 

I went with MSD, works fine. I would say if you are in the market anyway, you might as well upgrade to an aftermarket, be it Crane or MSD or whatever.

 

Is there a gain over the stock coil vs MSD or Crane???

 

get the msd, it looks cool. Dont think there is a real performance gain though, but it cant hurt either

 

what about some part numbers?

 

here you go
part #121-8231
gm single connector 96-99 vehicles

 

cool thanks

 

When my coil went out I put a MSD coil on it from a friend for a few days. I then put one on from Autozone. Well's brand I believe. No difference at all. Save the money and go with a stocker. The only reason you should need a "better" coil is when you're running big power. Although there have been freak instances where stock coils just wont work with somewhat stock cars. Either way, try both if you get real antsy.

I also bought an ICM from auto for $75 or so. Works fine.

 

Buy a GM coil. Just because something is "aftermarket" does not mean it's an upgrade. As far as the MSD looking cool... the only time you're gonna even look at it is when you're pulling it out of the box.

 

96-97 GM coils are very good coils. There is no gain to going aftermarket. IMO, OEM is the best you can get in regards to coils.

 

sweet guys, thanks, i just ordered the GM stock replacement.

now i have to decide what kind of plugs,

TR5
TR55
TR55 IX

 

TR55s are good and cheap. I've been running them since the summer and they're great so far!

 

TR55 Very high quality.

 

well im sold on these! hehe
