Welcome and thanks for joining us at FTE!

 

NGK TR 6

Lotta guys running low boost on a stock block with those plugs, and a lot of guys running high boost on built blocks with those plugs.

They are very forgiving and hold up really well.

+1. They're cheap too!

 

Ditto what the other guys said on the NGK's. The only drawback is that they are not an extended life material (platinum, iridium, etc.) and will require changing more often. That's not a big deal to some and it's a deal breaker to some. If I ran my truck hard a lot it would be worth a 2 hour plug change to have a friendly plug in there.

I run Densos in my truck and they work really well, but I'm on stock boost. They smoothed out the idle a little bit and the response feels a little more crisp.

 

Haha! Go built, I change my plugs about everytime I change the oil it seems like. I use the Denso's in it too!

 

i got the densos (it22) cost me $85 thats the most i have ever spent on plug's u got to pay to play lol

 

And these days that's cheap. It's not uncommon for an OE plug to be $25-30 each and some engines won't run right without them.

 

I run TR6's with my 4 lber and a Magnum Powers blower.
