Ok guys I would like to get some feedback from you. I am Vortech supercharged and I am going to change the plugs this weekend. What plugs do you recomend, and what gap do you like. I have searched and haven't found much info, so if you guys could chime in and give me your experience that would be great.

 

i use denso ik24s people say those foul after a while.. i have had no problem yet...most people told me to go with the ngk 7173. just make sure you set your gap right

 

I was thinking about those plugs, do you have to order them or can you find them at a store? What is your gap .32 .35?

 

.32 any lower and i was having issues when not in boost

 

I used to run IK24's at .032. I've changed over to NGK 7173's gapped at .030 when I uppped the boost. Both plugs are one step colder and work very well. I chose NGK's because they cost less and I replace them when I change the oil.

 

wow you must like to change your plugs then LOL, ok one more question can I go and by these plugs anywhere or do I have to order them

 

I order a few sets at a time from sparkplugs.com. Most auto parts stores don't have them in stock, but can usually get them special ordred in a few days.

 

sparkplugs.com order a couple of sets dirt cheap. paid like 16$ for 2 sets

 

Screw denso's I had mine have the ceramic fall apart once.

 

The Iridium plugs have been known to develop a high rpm miss and just lately, a thread was posted up saying one failed in NA application.

The NGK 7173 are copper and will need replacing far sooner for FI application. I'm using those with a gap of 0.034".
