86-95 Iannetti Ceramic Apex Seal, 0000-01-9113 Silver
Iannetti Ceramic Apex Seals are the ultimate apex seal for any rotary engine. They are extremely strong, very light, and do not wear into the rotor housings the way a steel apex seal can. They are perfect for turbo and naturally aspirated applications alike, and are available in either 2mm or 3mm variants and as single or two-piece design (we have found that the two-piece seals much better, but is more expensive). We use these seals in our #25 peripheral port 20B non-turbo race car. Price is PER apex seal (that's right, they cost this much EACH) and include dual-apex seal springs, but are well worth every penny if you want the longest life out of your engine.
Price is for 1 individual apex seal. You will need 6 for a 13B and 9 for a 20B
