Direct Hits plugs
 

Okay, so I have seen this site:
https://www.directhits.com/

It seems to be non-resistor plugs with RFI eliminators and a capacitor, claiming a bigger and better spark. I did note that they have the CARB and OBDII certifications, meaning they are not supposed to harm vehicles.

Specifically to my questions - has anyone used these, and how will they work on a CRX (88-91)? One guy claimed he got nothing using them, although it looks like they used to be bolt-ons for your own plugs. Now they appear to be a plug wire set plus the bolt-ons plus the plugs all in one package so you use the correct items.

Very curious. And yes I used the search - one post of a guy claiming they didn't work wasn't enough for me.

Thanks to anyone who replies - VERY curious about this one.

I have pulstar plugs, which are very similar. OEM size capaciter/gap based super spark plug. normally they're $25/ea (I have a buddy who makes them tho). putting them in didn't make any noticeable difference in mpg and the butt dyno saw mild gains....akin o going from old worn plugs to new ones except I already had new ones. in other words, REALLY not worth the price.
