Bosch +4s and i love them

 

NGK TR55s. I used AC Delco platinums before and had issues with the platinum "pucks" on the electrodes falling off. When we pulled my old engine to swap the 383 in, only one plug still had that "puck" on it...the other seven had disappeared.

 

Ditto, so I just switched to NGK TR5s. I just hope they last since it is such a bear of a job with these SLP headers.

 

I just got a set of Hooker longtubes put on...plug changes now take no more than 20 minutes.

 

Autolite 104's gapped at .032

For N/A autolite 106 is good, they are supposed to hold their gap very well.

 

Hi guys, i will be installing my MACs this month and ought to do a plug swap, what is your recommendation for a low mileage 97 car with just bolt ons? what does the gap mean? Thanks

AC DELCO PLATS here.

 

Autolite...whatever is cheapest; gaped @.50
Don't buy into the pay more for plugs game...although this last change I had to buy Bosch Plats; don't like them enough to buy again, no difference in the car between the $1 plug and the $2.25 plug except the cost. And, actually she feels more sluggish pre 3K RPMs now.

 

Autolite plugs here, I've run from a 103 to a 107, I'd stick with a 105/106 unless you have reasons otherwise.

 

I'm drooling! I gotta make that swap from the Shortys some time soon!!!

 

AC Delco Plats

 

NGK TR55 @ 0.40

 

I run Bosch plats because they are the shortest plug I could find.
